Low-lying excited states in the neutron-deficient isotopes 163Os and 165Os
Excited states in the neutron-deficient isotopes 163Os and 165Os were identified using the JUROGAM and
GREAT spectrometers in conjunction with the RITU gas-filled separator. The 163Os and 165Os nuclei were
populated via the 106Cd(60Ni,3n) and 92Mo(78Kr,2p3n) reactions at bombarding energies of 270 MeV and
357 MeV, respectively. Gamma-ray emissions from these nuclei have been established unambiguously using the
recoil-decay tagging technique and a coincidence analysis has allowed level schemes to be established. These
results suggest that the yrast states are based upon negative-parity configurations originating from the νf7/2 and
νh9/2 orbitals.peerReviewe
Transition probability studies in 175Au
Transition probabilities have been measured between the low-lying yrast states
in 175Au by employing the recoil distance Doppler-shift method combined with the selective
recoil-decay tagging technique. Reduced transition probabilities and magnitudes of transition
quadrupole moments have been extracted from measured lifetimes allowing dramatic changes
in nuclear structure within a low excitation-energy range to probed. The transition quadrupole
moment data are discussed in terms of available systematics as a function of atomic number
and aligned angular momentum.peerReviewe
