On M1-transitions from highly excited states
Authors:L V Groshev  A M Demidov
Abstract:This article is concerned with the probabilities of Mi-transitions from states created by the capture of thermal neutrons for even-odd and odd-odd emitting nuclei with A from 20 to 60. In the single-particle model, such transitions are forbidden with respect tol. A comparison with the probabilities of E1-transistions shows that in even-odd nuclei, the probabilities of forbidden Mi-transitions which we observed, did not differ much from the probabilities ofl-allowed M1-transitions for lighter nuclei.In the case of odd-odd nuclei, certain M1-transitions are characterized by a large number of quanta per single neutron capture and a large value of
