Abstract
Nuclear reactions induced in elemental copper by irradiation with charged particles accelerated to energies in the hundred-Mev range have been studied, and the reaction products cover a range from the region of the target nucleus to a region which is removed from the target nucleus by as many as forty or more nucleons. The yields of the various products were measured, and the results show that a large majority of the products result from reactions in which only a fraction of the total energy of the incident particle is left with the nucleus. The distribution of the amounts of the reaction products is in agreement with a picture of high energy nuclear reactions involving nuclear transparency and the idea that the nuclear reactions involve excitation following collisions and energy transfers between the individual nucleons in the impinging particle and the individual nucleons in the target nucleus. The results include recent work on the nuclear reactions induced by 340-Mev protons and some earlier qualitative work on the nuclear reactions induced by 190-Mev deuterons and 190- and 380-Mev helium ions.Keywords
