ENERGY LEVELS OF Bi$sup 210$ AND Po$sup 210$ AND THE SHELL-MODEL RESIDUAL FORCE
The low-lying energy level spectra of Bi/sup 210/ and Po/sup 210/ are calculated by using the j-j coupling shell model and a residual nucleon-nucleon Gaussian potential without a hard core deduced from the free two-nucleon potentials of BlattJackson and Brueckner-Gammel-Thaler. The spin-orbit force is neglected, but all direct and exchange components of the central and tensor forces are considered. Tensorforce effects are examined as a function of the range. A tensor force with reasonable range and strength accounts for the 1/sup - / state of the h/sub 9/2//, g/sub 9/2//, multiplet being the grou nd state of Bi/ sup 210/, instead of the O/sup -/ predicted by central forces. Eigenvalues and eigenfunctions are presented and compared with the experimental spectra. It is shown that the ground-state wave functions for Bi/sup 210/ and Po/sup 210/ are consistent with the RaE BETA -decay parameter i(r)/( sigma x r) and the measured magnetic dipole moment of Bi/sup 210/.
