Abstract

Strongly damped components have been studied in relatively light heavy ion reaction systems;20Ne(E lab=93, 120 and 146MeV)+50Cr,20Ne(E lab=146MeV)+54Cr and20Ne(E lab=146MeV)+92Mo,100Mo. The kinetic energy, angular and charge distributions have been observed for those products. The yields of symmetric-mass-splitting products for20Ne+50Cr were found about three times larger than those for20Ne+54Cr. There was also observed a similar difference in the cross sections of the symmetric-mass-splitting products between20Ne+92Mo and20Ne+100Mo reactions. In order to explain the bombarding energy dependence of the cross sections of symmetric-mass-splitting products by the transport theory, it was found necessary to assume that the mean life of the composite nucleus was dependent on the bombarding energy. However, the target isotope dependence of the cross sections could not be explained by such an assumption. They could be partly explained by fission calculations.
