Abstract: | Excitation function and mean projected recoil ranges of nuclei produced in the7Li and16O induced reactions on51V target were measured by conventional stacked foil and thick-target thick-recoil-catcher technique for bombarding energiesE ≤ 50.0 MeV for7Li ions andE ≃ 60.0-96.0 MeV for the16O ions. The measured recoil ranges are converted to momentum transfer. The momentum transfer information was used to get clues
about some aspects of the interaction such as complete and incomplete fusion reaction mechanism which correspond to full and
reduced momentum transfer respectively. The measured excitation functions are compared with the calculation based on the statistical
model which describes only equilibrium decay of the compound nucleus using the CASCADE code. The comparison of the CASCADE
code with the measured excitation functions for the residue radioisotopes51Cr and54Mn for the7Li +51V system indicates the reaction mechanisms is complete fusion of7Li with the target nucleus51V. Similarly the comparison of the CASCADE code with the measured excitation functions of the residue radioisotopes for the
system16O +51 V indicates that the four reaction mechanisms (i) complete fusion of16O, (ii) incomplete fusion of12C, (iii) incomplete fusion of8Be and (iv) incomplete fusion of4He respectively with the target might be contributing to reaction cross sections. |
