Estimation of the spallation-residue angular momentum in p+Ta, Re reactions
Original language description
Yields and cross-sections for the radioactive isotope production have been, determined via gamma-activity measurements after irradiation of the Ta and Re targets by protons with energies from 100 to 660 MeV. Mass-distribution of the reaction products contains two wide peaks corresponded to the spallation and fission product nuclei, respectively. High-spin Hf and Lu isomers are among the detected nuclides. The spallation-residue angular momentum, I, has been estimated basing on the determined isomer-to-ground state ratio, sigma(m)/sigma(g), and using, known systematics of sigma(m)/sigma(g), versus I. Non zero value of spin I should increase a probability of fission. Measured fission-to-spallation ratio is indeed higher than predicted by the Monte Carlocode simulation without angular momenta in account.
