Nuclear multiplets in light odd-odd nuclei and their manifestation in ?-transitions occuring after thermal neutron capture

Abstract

We consider those states of odd-odd nuclei with A < 60 which differ in their total angular momentum J, but whose configurations contain an odd proton and an odd neutron with given angular momenta jp and jn. We review the experimental data on the basis of which one may assume the existence of such nuclear multiplets lying close to the ground states. We compare the γ-decay schemes of those states of even-odd (odd neutron) and odd-odd nuclei with A < 60 which arise as a result of the capture of thermal neutrons. The characteristics of γ-transitions in odd-odd nuclei are explained on the basis of multiplet concepts.
