Term Values in V II and Mn II

Abstract

The term values for $d^{3}s$ and $d^{5}s$ have been calculated in Russell-Saunders coupling. For some of the terms of the same kind in $d^{5}s$, only the sum of the energies is obtained. The first approximation to the separations of the levels is also found for $d^{3}s$. The theoretical formulas including Ostrofsky's results for $d^4$ are then applied to the observed values of V II and Mn II.
