Abstract: | The present thesis focuses on the experimental measurements of evaporation newlineresidue (ER) cross-sections and fission mass distributions for the 48Ti + 140,142Ce reactions to understand the influence of neutron shell closure on the newlinecompound nucleus (CN) formation. The measured ER cross-sections for 48Ti + 140Ce (NT= 82) system are found to be very close to those of 48Ti + 142Ce (NT=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 newlinesystems which can be attributed to the small values of the shell correction newlineenergies in the entrance channel. Statistical model calculations are performed newlineto interpret the experimental results. Further, comparison of the present newlineresults with those from a reaction with higher mass asymmetry in the entrance newlinechannel shows no evidence of quasi-fission in the present systems. Widths of the mass distribution for the above systems have been correlated with the ER cross section measurements. newline newline |
