Neutron-neutron and proton-proton residual interactions in lowest lying multiplets of 210Pb and 210Po

Finite range central force of Yukawa shape with exchange terms have been used to calculate the energy levels of 210Pb and 210Po nuclei. Shell model wave functions with harmonic oscillator radial parts were employed for the calculations of the energy matrix elements. Comparisons between theoretical calculations and the experimental data are presented. Forces with fitted parameters reveal that the triplet odd parts are attractive in contrast to Rosenfeld forces which are repulsive. (author)
