Abstract The results of a radlochemical study of the disintegration products in copper disintegration induced by 680-Mev protons is presented; the yields of nuclei which were not directly observed are obtained by extrapolation. This procedure makes it possible to obtain a complete picture of the residual products and to draw certain conclusions with respect to the basic characteristics of the process; 1) the total cross section for the disintegration of copper is 0,6 · 10−24 cm2 corresponding to 65% of the geometric cross section; 2) the main contribution in the total cross section for the production of disintegration products in copper is due to cobalt, nickel and copper (60%); 3) the isotope yield is increased as the region of stability is approached; 4) in the disintegration process, protons and neutrons are emitted in almost equal numbers Σn/σp= 1.3; 5) the emission of an α-particle is more probable than the subsequent emission of four nucleons; 6) nuclear structure has no effect on the disintegration of nuclei by high energy particles. By appraising the characteristic features of the disintegration of copper by 680-Mev protons in conjunction with the data obtained in studies of the products of copper disintegration induced by particles with energies from 130 Mev to 2.2 Bev, it is possible to evaluate the effect of the energy of the bombarding particles on the nature of the disintegration process in this element.
