Study of Nuclear Structure by (t, nγ) and (p, γ) Reaction

Abstract

The level schemes of V⁵⁰, Mn⁵⁴, Co⁵⁸ and Fe⁵⁷ have 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.
