Abstract

The population of the superdeformed bands in {sup 191} Hg has been measured for two reactions with different mass asymmetry. No entrance channel effect was observed, in contrast to similar measurements in the A=150 region. To further elucidate this problem, the entry distribution for the superdeformed band in {sup 192}Hg was measured and a monte Carlo model for the feeding was developed. The simulations suggest that the decision on trapping in the superdeformed well is made at the barrier between the normal and superdeformed wells rather than at the entry point. (author). 9 refs., 3 figs.
