| dc.description.abstract | The lifetimes and lifetime limits of the low-lying excited states up to and including the 61+ levels in 196, 198Pt were determined by the recoil-distance method (RDM). Gamma-ray angular distributions in 198Pt were also measured. These states were populated by multiple Coulomb excitation using 220 MeV 58Ni ion beams and the measurements were carried out in coincidence with back-scattered projectiles. The measured mean lives of the states and B(E2) values inferred for the transitions between levels are presented. These specific findings, and the observed structure systematics obtained from the combination of the present results and those of prior workers for the even 194-198Pt isotopes, are critically compared with our structure calculations employing the interacting boson approximation (IBA) model incorporating a symmetry-breaking quadrupole force; evaluative comparisons are also made with boson expansion theory (BET) calculations. | en |

Tamura for providing their boson expansion theory predictions for 19'*'1°6'198pt prior to publication, as well as for helpful discussions. We are also grateful to Professor J. O. Newton and the research staff of the Department of Nuclear Physics, Australian National University, for the hospitality and aid provided at the 14UD Pelletron accelerator, and to D. Conley for his assistance during the experimental runs. Three of us (A.E.S., D.L.K., and C.G.R.) are appreciative of the support of Commonwealth Postgraduate Research Awards.
