摘要
Measurements of excitation functions were done for the evaporation residues populated in 14N+124Sn system at low energy. The present analysis shows the appearance of incomplete fusion by the breakup of non-alpha cluster structured projectile 14N into alpha +10B. A correlation between the combined effects of total asymmetry and ZPZT has been studied through three new parameters total asymmetry (STAS), Coulomb asymmetry parameters; ZPZT/STAS and ZPZT.STAS. These new parameters were found more sensitive and effective to encounter the combined effects of coulomb interactions and entire asymmetry effect of the system on incomplete fusion dynamics. The complete fusion and total fusion cross-sections of two systems 14N+124Sn and 16O+124Sn have been reduced using two different standard reduction procedures, which shows that the incomplete fusion probability for reactions induced by projectile 16O is generally larger than 14N induced reactions. The experimental fusion functions are found to be suppressed as compared to universal fusion function for systems 14N+124Sn and 16O+124Sn. The different values of suppression factor for projectiles 14N and 16O indicate that the probability of alpha -breakup is different for these projectiles. Further, the total fusion functions for systems 14N+124Sn and 16O+124Sn agree well with the universal fusion function. However, the present results clearly show that the shell closure of nuclei also affect the low energy incomplete fusion dynamics along with the structure of projectile.
