Intermediate Coupling in the1p-Shell

Abstract

The region between ${\mathrm{He}}^4$ and ${\mathrm{O}}^{16}$ is treated for the case of intermediate strength of spin-orbit coupling and central two-body interaction. Energy levels are presented as a function of the relative coupling strength parameter, $\frac{a}{K}$. Static electromagnetic moments are also computed as functions of $\frac{a}{K}$. Comparison with experimental results gives a fairly good picture, and determines a definite behavior for $\frac{a}{K}$ as a function of mass number. A possible interpretation of this behavior is suggested.
