The level structure of 102Rh has been investigated using the EUROGAM Phase2 array. Bands observed up to high spins are discussed in terms of band terminations. 102Rh is the first doubly odd nucleus below Z = 50 in which band terminations are established.
The highest-spin discrete states (I ∼ 60 ℏ and Ex ∼ 30 MeV) in normal deformed nuclei have been observed in the rare-earth isotope 156Dy using the 124Sn(36S,4n) reaction in conjunction with the GAMMASPHERE spectrometer. The positive parity yrast sequence appears to evolve smoothly from a prolate (collective) towards an oblate (non-collective) shape, in contrast to the sudden shape change observed
Four new superdeformed bands have been found in the nucleus 86Zr. The good agreement between experiment and configuration-dependent shell correction calculations suggests that three of the bands have triaxial superdeformed shapes. Such unique features in mass A ∼ 80 superdeformed bands have been predicted, but not observed experimentally until now. A fourth band in 86Zr is interesting due to a fai
Excited states in [Formula Presented] have been observed with the Stony Brook array of six Compton-suppressed HPGe detectors and the [Formula Presented] reaction at 60 MeV using a thick target. New excited states which decay solely towards the [Formula Presented] ns, [Formula Presented] isomer have been identified using time-correlated spectroscopy. The previously known level scheme has also been
The relative properties of smooth terminating bands observed in the A ∼ 110 mass region are studied within the effective alignment approach. Theoretical values of ieff are calculated using the configuration-dependent shell-correction model with the cranked Nilsson potential. Reasonable agreement with experiment shows that previous interpretations of these bands are consistent with the present stud
Six rotational bands in the odd-odd nucleus 174Ta have been populated with the 160Gd(19F,5n) reaction. High-spin states were identified using the NORDBALL array. Both signatures of the doubly decoupled π1/2- [541 ] ⊗ v1/2- [521] band and semi-decoupled π1/2- [541] ⊗ v7/2+ [633] band are observed, in addition to the high-K couplings of the π9/2- [514] ⊗ v7/2+ [633], π9/2- [514] ⊗ v5/2- [512], π7/2+
Lifetimes of states in two rotational bands in 108Sn and one in 109Sb have been determined using the Doppler shift attenuation method. The deduced quadrupole moments for the states are in excellent agreement with cranked Nilsson model predictions, which imply a gradual change in the nuclear shape from collective near-prolate at medium spin to noncollective oblate at high spin. This change results
High-spin states in the odd-[Formula Presented] nucleus have been investigated with the [Formula Presented] reaction at 94 MeV using the Chalk River [Formula Presented] array. Three decoupled [Formula Presented] rotational bands extending to spins [Formula Presented] in the range [Formula Presented] have been identified and connected to known low-lying states. Experimental observations for the mos
The level structure of 102Pd has been investigated using data collected with the Eurogam 2 array. Several cascades of γ-rays have been established up to high spins. Termination of rotational bands has been observed at Iπ = 28 - and 32 +, and tentatively at Iπ = 38+ and 42+. The nucleus 102Pd is the first case where rotational bands built on valence space configurations are followed from spin close
High-spin states in the nucleus [Formula Presented]Te have been studied with the reaction [Formula Presented]Ni[Formula Presented]Fe,[Formula Presented] at 236 MeV using an early implementation of the Gammasphere array. Three rotational bands extending to spins [Formula Presented] and excitation energies [Formula Presented] MeV have been identified and connected to known low-lying states. In the m
Semi-decoupled bands based on the πh9/2 ⊗ vi13/2 configuration are observed in 162Tm,164Tm and 174Ta. Spins assigned to these bands imply an inversion of the expected signature splitting, which is interpreted as being the result of a residual proton-neutron interaction.
Assuming that the wave function of the [Formula Presented] ground state of [Formula Presented]Ra is quadrupole-octupole deformed with [Formula Presented] [Formula Presented] [Formula Presented] [Formula Presented], and [Formula Presented] having the optimum values of 0.129, 0.075, 0.004, 0.10, and 0.01, respectively, its amplitude in the wave functions of the [Formula Presented] [Formula Presented
High-precision lifetime measurements have been performed in superdeformed (SD) bands of 151,152Dy and 151Tb with the Doppler-shift attenuation method. Differences found in the quadrupole moments Q0 of the yrast SD bands are understood in terms of shape polarization effects by the high-N intruder orbitals. Q0 moments are also presented for three excited SD bands in 151Dy. Recent calculations can ac
Four new superdeformed (SD) bands have been observed in 147Gd using the EUROGAM II spectrometer. By comparison with 146,148,149Gd SD bands, we use the effective alignment to assign excited band configurations, with the support of the Nilsson-Strutinsky cranking formalism. The effect of the crossing of the [642]5/2 and [651]1/2 neutron orbitals lying just below the magic N= 86 SD shell gap has been
Teledermoscopy (TDS) offers an efficient alternative to face-to-face assessment of suspicious skin lesions. Although diagnostic accuracy in TDS is relatively high, further improvement is desirable to reduce the risk of overlooked skin cancers and unnecessary interventions of benign lesions. Image enhancement (IE), i.e. digital modification of different parameters of an image, may potentially impro
The properties of rotational bands in the A ∼ 110 (Z ≥ 50 N ∼ 56-65) mass region are investigated within the configuration-dependent shell-correction approach with the cranked Nilsson potential. It is shown that in nuclei with Z > 50, N < 60, smooth terminating bands based on two proton holes in the g9/2 subshell might be observed over a wide spin range up to termination. In the N > 60 nuclei, the
Intruder rotational bands have been investigated to high frequency in 10951Sb. Five decoupled (ΔI=2) bands extending to rotational frequencies above 1.4 MeV/ℏ have been observed. At the highest frequencies, the script J sign(2) dynamic moments of inertia for four of these bands are seen to decrease steadily to unexpectedly low values, script J sign(2) ∼ 10 ℏ2 MeV-1. These four bands, which are int
For nuclei with only a few particles outside closed shells, rotational bands might be formed in configurations with holes in the core. Common properties of bands of this kind with hole(s) in the high-j shells, f7/2 g9/2 and h11/2 are discussed and specific examples are compared with experiment. At superdeformation it is suggested that an approximate decoupling factor for the π[301 1/2] and ν[411 1
We have measured lifetimes and deduced deformation parameters for rotational bands in 133Pm by the Doppler-shift attenuation method. A strongly coupled band based on the configuration with a hole in the g9/2 orbital has deformation parameter β2 = 0.40 (5), which is comparable to or larger than typical superdeformed bands in the A ∼130 region. We observe this band in 133Pm down to its I=K=9/2 bandh
Metastasis is the most common cause of cancer patient deaths. It is a complex process strongly influenced by the extracellular matrix (ECM). A mass spectrometry analysis comparing ECM proteins from healthy mouse lungs versus metastatic lungs has previously been performed, and the basement membrane (BM) component nidogen-1 has been identified to be one of the most downregulated ECM proteins in meta
