The Spin Dipole Interaction in Odd-Odd Nuclides
In this paper, I wish to discuss some of the systematics of the spin-dipole term in the splitting of multiplets in odd-odd nuclides. Since the introduction of the Paar model for treating odd-odd nuclides in 1979, most of the attention has been focussed on the quadrupole term which produces the now-familiar parabolic splitting.1 While the need for yet a third cubic term has been obvious for nuclides that are quite near double closed shells, the dimensions of the effects of the spin dipole term have not been explored in a general and systematic way. Inasmuch as some of the cleanest doublets are found in the mass 100 region in the Nb nuclides, this discussion would seem appropriate to this conference.
