Abstract:The competition between pn and d evaporation leading to production of the same residual nuclei has been measured for 9 heavy-ion induced nuclear reactions, each at several bombarding energies, for target-projectile combinations resulting in compound nuclei 19 ? A ? 71. An association of the ratio σpn/σd with the maximum excitation energy available to the residual nucleus demonstrates a systematic trend, the significance and potential applications of which are investigated.
