Exploring $\beta^+$ decay/EC residues in $^{118}$Sn($^{12}$C,x)$^{130}$Ba reaction
Abstract
The fusion cross-sections of Ba, Cs, Xe and I residues, populated via n, pn, n, and pn channels, have been measured in C+Sn system at E 65-85 MeV. For an insight into the formation and decay modes of these residues, experimentally measured cross-sections have been analyzed in the framework of theoretical model codes PACE4 and EMPIRE. The cross-sections of pn (Cs), xn (Xe), and pn (I) channels have been found to be substantially fed from their higher charge isobars via decay and electron capture. In order to deduce the contribution of higher charge isobars in the population of these residues, the independent cross-sections of evaporation residues have been calculated using the prescription of Cavinato and compared with that calculated using theoretical model codes. It has been found that the PACE4 and EMPIRE calculations fairly reproduce the independent cross-sections of evaporation residues within the experimental uncertainties. Interestingly, it has been found that the -emitting channels, contrary to established findings in reactions involving cluster projectiles (e.g., C, O, etc.) at low incident energies, display negligible contribution of incomplete fusion (ICF). A comparison of incomplete fusion fraction as a function of entrance channel mass-asymmetry for reactions involving C projectile with nearby targets indicates dissimilar behavior of Sn target.
