Re-interpretation of the structure of $^{184}$Pt

ORAL

Abstract

The traditional interpretation of the light Pb, Hg and Pt isotopes invokes the concept of proton intruder states from above the Z=82 shell gap. However, recently, a single configuration IBA-1 Hamiltonian was used to test this interpretation of the light Pt isotopes [1]. Without any need for intruder states, these results showed excellent agreement in both energies and B(E2) values. Among these Pt isotopes, $^{184}$Pt lacks sufficient data on relative B(E2) values. Therefore, to obtain further information on this nucleus, we carried out a $\beta$-decay experiment at the Yale Moving Tape Collector at WNSL using the $^{175}$Lu ($^{16}$O,7n) reaction at 132MeV. After producing parent $^{184}$Au, we observed transitions in $^{184}$Pt particularly those from low-spin non-yrast states were observed using clover detectors from YRAST Ball. The results of this work will be discussed. This work was supported by US DOE Grant No.DE-FG02-91ER-40609 \\ \\ \mathbb{[1]} E.A. McCutchan, R.F. Casten, and N.V. Zamfir, Phys.Rev.C (in press).
