Title: Observation of γ-vibrations and alignments built on non-ground-state configurations in ¹⁵⁶Dy

Abstract

Rotational structures in ¹⁵⁶Dy have been populated with the ¹⁴⁸Nd (¹²C, 4n) ¹⁵⁶Dy reaction at 65 MeV and the resulting γ-ray transitions observed with Gammasphere. The even- and odd-spin members of the K^π=2⁺ γ-band are observed to 32⁺ and 31⁺ respectively and the members of a possible γ-vibration built on the aligned S-band are observed to spins 28⁺ and 27⁺. An even-spin positive-parity band, observed to spin 24⁺, is a candidate for an aligned S-band built on the seniority-zero configuration of the 0₂ ⁺ state at 676 keV.

Investigation of negative-parity states in ${}^{156}{Dy}$ : Search for evidence of tetrahedral symmetry

Journal Article Hartley, D. J. ; Riedinger, L. L. ; Janssens, R. V. F. ; ... - Physical Review C

In this paper, an experiment populating low/medium-spin states in ¹⁵⁶Dy was performed to investigate the possibility of tetrahedral symmetry in this nucleus. In particular, focus was placed on the low-spin, negative-parity states since recent theoretical studies suggest that these may be good candidates for this high-rank symmetry. The states were produced in the ¹⁴⁸Nd(¹²C,4n) reaction and the Gammasphere array was utilized to detect the emitted γ rays. B(E2)/B(E1) ratios of transition probabilities from the low-spin, negative-parity bands were determined and used to interpret whether these structures are best associated with tetrahedral symmetry or, as previously assigned, to octupole vibrations.

In particular, focus was placed on the low-spin, negative-parity states since recent theoretical studies suggest that these may be good candidates for this high-rank symmetry. The states were produced in the 148 Nd ( 12 C , 4 n ) reaction and the Gammasphere array was utilized to detect the emitted γ rays. B ( E 2 ) / B ( E 1 ) ratios of transition probabilities from the low-spin, negative-parity bands were determined and used to interpret whethermore »« less

I {approximately} 60 {dirac_h} in {sup 156}Dy : competition between collective and terminating structures at very high-spin.

Journal Article Kondev, F G ; Riley, M A ; Janssens, R V. F. ; ... - Phys. Lett. B

The highest-spin discrete states (I {approx} 60 {Dirac_h}and E{sub x}{approx}30 MeV) in normal deformed nuclei have been observed in the rare-earth isotope {sup 156}Dy using the {sup 124}Sn({sup 36}S,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 in the isotone {sup 158}Er. Terminating states are identified in the negative parity sequences at I{sup {pi}}=52{sup -} and 53{sup -} and specific multi-particle-hole configurations are assigned by comparison with cranked Nilsson-Strutinsky calculations.

First observation of rotational structures in ${}^{168}{Re}$

Journal Article Hartley, D. J. ; Janssens, R. V. F. ; Riedinger, L. L. ; ... - Physical Review C

We assigned first rotational sequences to the odd-odd nucleus ¹⁶⁸Re. Coincidence relationships of these structures with rhenium x rays confirm the isotopic assignment, while arguments based on the γ-ray multiplicity (K-fold) distributions observed with the new bands lead to the mass assignment. Configurations for the two bands were determined through analysis of the rotational alignments of the structures and a comparison of the experimental B(M1)/B(E2) ratios with theory. Tentative spin assignments are proposed for the πh_11/2νi_13/2 band, based on energy level systematics for other known sequences in neighboring odd-odd rhenium nuclei, as well as on systematics seen for the signaturemore »« less
