Nuclear reactions of medium and heavy target nuclei with high-energy projectiles

Nuclear reactions induced by 3·65 A GeV¹²C-ions and 3·65 GeV protons on target elements⁵⁵Mn,⁵⁹Co,^nat Ni and^natCu were investigated by using the foil stack activation technique and Ge(Li) gamma-ray spectroscopy. Charge dispersions and mass-yield distributions of radioactive residues were obtained from the parametrization of measured spallation cross sections. Discussion of results from this and other radiochemical reactions of high-energy protons and¹²C-ions with complex nuclei is presented in terms of the concepts of limiting fragmentation and factorization.
