STUDY OF NUCLEAR STRUCTURE BY (T NGAMMA) AND (P GAMMA) REACTIONS

The level schemes of V50, Mn54, Co58 and Fe57have been investigated with the Ge(Li) detectors and the scintillation counters by using triton induced reactions. These results were also compared with the (p, γ) reactions. Gamma-rays at energies of 92, 122, 158 and 225 keV on V50: 55, 156, 212 and 250 keV on Mn54: 112 and 367 keV on Co58: were observed. By using the residual activities the reaction characteristics of the triton induced reaction were investigated. The spin distribution in the Mn55(t, n)Fe57 reaction is calculated with the compound nucleus model and the ratio of the population probability obtained is 5/8 for the J=7/2 and J=5/2 states on Fe57. New gamma-rays which expected from the rotational model on Fe57 were searched for with this reaction. But they were not observed. © 1969, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
