Abstract
The reaction is investigated with alpha particles in the energy range 35-63 MeV. The measured cross sections are compared with the cross sections for , a reaction which proceeds through the same compound nucleus, . At fixed excitation energy of the compound nucleus (C.N.), the alpha-induced reaction has a higher cross section for MeV. The cross-section ratio increases from 4.4±1.0 at MeV to 6.3±1.4 at MeV. Part of this significant difference is shown to be due to angular-momentum effects in compound-nuclear processes. The balance is attributed to the multinucleon pickup by the He ion. A similar effect is observed in the reactions and .
