The population of the highly-deformed band in 133Nd has been studied using the reactions32S +105Pd and 60Ni +77Se to form the compound nucleus137Sm at comparable excitation energy. Experimental results do not show any dependence on the entrance-channel mass asymmetry, in agreement with recent results for135Nd and at variance with those for the 147,148Gd and 152Dy nuclei. The experimental data on the entrance-channel dependence of the population of highly- and super-deformed bands in the mass regions A ˜130,150and190 are discussed in terms of dynamical effects which occur during the formation process of the compound nucleus as well as in the fission channel.

Abstract
The population of the highly-deformed band in 133Nd has been studied using the reactions32S +105Pd and 60Ni +77Se to form the compound nucleus137Sm at comparable excitation energy. Experimental results do not show any dependence on the entrance-channel mass asymmetry, in agreement with recent results for135Nd and at variance with those for the 147,148Gd and 152Dy nuclei. The experimental data on the entrance-channel dependence of the population of highly- and super-deformed bands in the mass regions A ˜130,150and190 are discussed in terms of dynamical effects which occur during the formation process of the compound nucleus as well as in the fission channel.
