Abstract

The energy and angular distributions of alpha particles produced by 14.6 MeV neutron bombardment of 103Rh, 139La, 141Pr, 159Tb and 209Bi have been measured. While data on 103Rh are inconclusive, both the energy spectra and the angular distributions of all other reactions show a direct surface process, possibly of a knock-out nature. A simple model has been used to calculate the probability of formation of alpha particle clusters on the surface of heavy nuclei, and the lifetime of these clusters has been estimated.
