FORMATION OF 7Be IN NUCLEAR REACTIONS INDUCED BY 85-MeV PROTONS

Abstract

Cross sections were measured for the formation of ⁷Be in targets bombarded with 85-MeV protons. The variation of these cross sections with the mass and neutron-to-proton ratio of the target was investigated.Cross-section calculations were performed on the assumption that ⁷Be is emitted from the irradiated target as an evaporated particle. Calculated and measured cross sections were in good agreement for medium and heavy targets (A > 55). The calculation underestimated the production of' ⁷Be in light targets (27 < A < 55).
