Dp. Diprete et al., SEARCH FOR HIGH-LYING OCTUPOLE STATES AND OCTUPOLE FRAGMENTATION IN PT-196 WITH THE (N, N'GAMMA) REACTION, Physical review. C. Nuclear physics, 48(6), 1993, pp. 2603-2606
The firm determination of spins and parities of possible octupole stat
es at excitation energies between 2 and 3 MeV is crucial for understan
ding the anomaly in the behavior of low-energy-octupole states which o
ccurs in the Pt-Hg region. The Pt-196(n,n'gamma) reaction has been use
d in an effort to identify four possible octupole states observed prev
iously in the (p,p') reaction and tp make spin-parity assigments.
