Extent of Complete and Incomplete Fusion on 12,13C + 208,207Pb Systems above the Coulomb Barrier

Kushal Kalita

Abstract


The complete and incomplete fusion cross sections are being measured for 12,13C + 208,207Pb systems to investigate the influence of break up at above barrier energies which form the same compound nucleus at the same excitation energies. The α-active heavy reaction products were measured for most dominant reaction xn-channels along with fission cross sections which originate almost exclusively from the complete fusion (CF). The results from the present systems show substantial components from incomplete fusion in addition to CF. The CF cross-section is suppressed by 12 ± 2% for 12C and 3 ± 2% for 13C compared with the SBPM calculations. A systematic variation of the suppression of CF for reactions of weakly bound nuclei 6,7Li, 9Be, 10,11B and 12,13C on target of 207,208Pb and 209Bi is being found as a function of the break up threshold energy.

Keywords: complete fusion, incomplete fusion, nuclei, SBPM calculations
