Incomplete Fusion Probability Research Articles

Linear momentum transfer in incomplete fusion reactions of 12C and 13C with 181Ta

Recoil range distribution of evaporation residues formed in complete and incomplete fusion of 82.5 MeV 12C and 13C with 181Ta have been measured by recoil catcher technique followed by off-line gamma-ray spectrometry. The recoil range distributions of incomplete fusion products were found to be in good agreement with that simulated on the basis of direct surface transfer reaction model. The cross-sections for complete and incomplete fusion were delineated from the measured excitation function data at the same beam energy. The fraction of incomplete fusion in the total cross-section was found to be more in the case of 12C than that in the case of 13C indicating the dependence of incomplete fusion probability on the cluster structure of the projectile.

Complete and incomplete fusion reactions in the [formula omitted] C [formula omitted] Tm

Excitation functions of evaporation residues produced in 12 C + 169 Tm reaction have been measured at several beam energies in the range of 60–84 MeV using recoil catcher technique followed by off-line gamma-ray spectrometry. Comparison of the experimental excitation functions with those calculated using the statistical model code PACE2 revealed dominance of incomplete fusion in the cross section of alpha-emission products. Measurement of recoil-range distributions of evaporation residues at 84 MeV beam energy corroborated these observations. Analysis of the cross sections of incomplete fusion products showed that these reactions are associated with peripheral collisions. Comparison of the present data with similar data on 16 O + 165 Ho system revealed that incomplete fusion probability is more in a mass asymmetric system than in a mass symmetric system.
