A Study of Complete and Incomplete Reactions of 12C + 169Tm System at Energy Range ≈ 4.16-7.5 Mev/Nucleon
Abstract
In this paper an attempt was to measure, the excitation functions of 169Tm(12C, 4n)177Re, 169Tm(12C, 5n)176Re, 169Tm(12C, αn)176Ta, 169Tm(12C, α2n)175Ta , 169Tm(12C, α3n)174Ta , 169Tm(12C, α4n)173Ta, and 169Tm(12C, 2α2n)171Lu reaction channels populated in the interaction of 12C projectile with 169Tm target were considered in order to investigate the mechanisms of complete and incomplete fusion reactions. The theoretically predicted excitation functions using PACE4 code were compared with the previously measured excitation functions. For non alpha emitting channels cross section values predicted by PACE4 in general were found to be in good agreement with the experimentally measured values. However, for alpha-emitting channels the measured cross-section values were found to be higher than the values predicted by PACE4. The observed disagreement may be credited to projectile break up in the vicinity of nn interaction. Keywords: alpha emitted, CF reaction, excitation functions, heavy ion fusion, incomplete fusion reaction, non alpha emitted
