摘要：

Excitation functions of evaporation residues produced in C-12 + Tm-169 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 O-16 + Ho-165 system revealed that incomplete fusion probability is more in a mass asymmetric system than in a mass symmetric system.
