Abstract
nExcitation function measurements have been done for the evaporation residues populating in the system 18O +144Sm. For this purpose, the stacked foil activation technique has been used subsequently accompanied by offline γ-ray spectrometry. The analysis of the experimental cross section of three evaporation residues 158Tm (p3n), 157Tm(p4n), and 155Ho(ap2n) has been donein the light of theoretical code PACE-4. Current findings demonstrate that the experimental cross sections of evaporation residues formed via xn and pxn-emission channels follow the PACE-4 predictions, confirming that these evaporation residues are produced exclusively by complete fusion. Similarly, the cross sections of the evaporation residues generated via α-emission pathways exhibit notable enhancement in contrast to the code predictions. The increase in cross sections seen can be credited to the fragmentation of the projectile 18O resulting in incomplete fusion. It has also been observed that there is a likelihood for the projectile to experience fragmentation i.e.,18O into 14C+ α increases as the energy of the projectile increases.
