Abstract

Excited levels of {sup 141}Xe, populated in spontaneous fission of {sup 248}Cm, were studied by means of prompt {gamma}-ray spectroscopy, using the EUROGAMM2 array. Level scheme of {sup 141}Xe obtained in this work shows patterns characteristic of simplex symmetry with s = +i and s = -i bands present but low value of D{sub 0} moment indicates that octupole correlations in Xe isotopes are systematically lower than in Ba nuclei.

Abstract

Excited levels in 133Sn and 134Sb, populated in spontaneous fission of 248Cm, were studied by means of prompt-γ spectroscopy, using the EUROGAM 2 multidetector array. The neutron i13/2 single-particle energy has been determined for the first time in the 132Sn region. The energy of the h9/2 neutron level, proposed previously, has been confirmed.

Abstract

By analysis of fission product gamma-ray data measured at Eurogam II using a Cm-248 source, yrast levels up to about 2 MeV in the N=84 three-particle nucleus Sb-135 have been identified. These levels are interpreted as pi g(7/2)nu f(7/2)(2) and pi g(7/2)nu f(7/2)h(9/2) states with the help of shell model calculations using empirical nucleon-nucleon interactions.
