Abstract

The binding energy of the excitonic molecule is calculated as a function of electron-to-hole mass ratio and of anisotropy in the hole bands. A variational wave function is used which is a product of a Hylleraas and Ore correlated excition function and an overlap function of the hole-hole separation. The results are tabulated for CuCl, CuBr, ${\mathrm{Cu}}_{2}$O, and for a number of II-VI compounds.
