摘要：

Evaporation residue (ER) cross-sections have been measured for the Ti-48 + Ce-140,Ce-142 reactions to understand the influence of neutron shell closure on compound nucleus (CN) formation. The measured ER cross-sections for Ti-48 + Ce-140 (N-T= 82) system are found to be very close to those of Ti-48 + Ce-142 (N-T= 84) near the Coulomb barrier. The results show that the effect of shell closure in the target nucleus on fusion cross-sections is negligible for the present systems which can be attributed to the small values of the shell correction energies in the entrance channel. Statistical model calculations are performed to interpret the experimental results. Further, comparison of the present results with those from a reaction with higher mass asymmetry in the entrance channel shows no evidence of quasifission in the present systems.
