SPIN–ORBIT INTERACTION IN NUCLEI

Abstract

Brueckner's theory of nuclear structure has been used to estimate the spin–orbit interaction of a single nucleon interacting with the core arising from the tensor force of the two-body interaction. Using Yamaguchi's separable two-body interaction, the doublet splitting for Ca⁴¹ and O¹⁷ has been calculated (i) in the first Born approximation and (ii) with an exact solution of the reaction matrix in which the exclusion principle has been taken into account. It is found that the values of the splittings calculated exactly are smaller than the experimental values.
