Somep- andd-Shell Nuclei in Intermediate Coupling

The theory of intermediate coupling has been applied to nuclei having either two particles or "holes" in the first $p$ or $d$ shell, such as ${\mathrm{He}}^6$, ${\mathrm{Li}}^6$, ${\mathrm{N}}^{14}$, ${\mathrm{C}}^{14}$, ${\mathrm{O}}^{18}$, ${\mathrm{F}}^{18}$, ${\mathrm{Ca}}^{38}$, and ${\mathrm{A}}^{38}$. A central nucleon-nucleon interaction of the form $\mathrm{}(mP+nQ)V\left(r_{12}\right)$, where $P$ denotes the Majorana and $Q$ the Bartlett operator, is assumed and calculations have been carried out for the exponential, Yukawa, and Gaussian types of potential $V\left(r_{12}\right)$ with various "ranges." The coefficients $m$, $n$ and the constants of the potential $V\left(r_{12}\right)$ have been estimated from data for two free nucleons.
