Evaporation residue cross-section measurements for ⁴⁸TI+^142,150Nd, ¹⁴⁴Sm systems using HYRA facility

For understanding the reaction mechanism involving heavy compound nuclei, we have performed measurements of the evaporation residue (ER) cross-sections for the (i) ⁴⁸Ti+¹⁵⁰Nd→¹⁹⁸Pb, (ii) ⁴⁸Ti+¹⁴²Nd→¹⁹⁰ Pb and (iii) ⁴⁸Ti+¹⁴⁴Sm→¹⁹²Po systems leading to compound nuclei around Z_CN=82 region. Shell effects may favor the survival probability in a fusion-fission reaction. Here, we investigate the effect of proton shell closure Z_CN=82, deformation effects through the ER cross-section measurements. It is conjectured that proton shell closure Z_CN=82 may lead to enhanced ER production and may help in the synthesis of heavy nuclei
