Abstract
Measurements of prompt Doppler-corrected deexcitation rays from uniquely identified fragments formed in fusion-fission reactions of the type are reported. The fragments were identified in both and using the variable-mode, high-acceptance magnetic spectrometer VAMOS. States built on the characteristic neutron configurations forming high-spin isomers ( and ) in are presented and compared with the predictions of shell-model calculations using a new effective interaction in the region of and .
