Abstract
The mean number ⌨Nb〉 of particles evaporated in the interaction of 22Ne, 32S, and 56Fe nuclei with photoemulsion nuclei was measured as a function of the number of alpha particles emitted within the fragmentation cone. It is found that ⌨Nb〉 decreases with increasing number of the alpha particles and increases with increasing number of projectile nucleons involved in the interaction with a target nucleus and that ⌨ Nb〉 is a linear function of the excitation energy Eex of the target-nucleus residue. The maximum experimental value of the mean number of evaporated particles is ⌨Nbmax〉 ≅ 12–13, which corresponds to Eexc ≅ 540 ± 60 MeV.
