Spin-orbiting splitting of the copper halides and its volume dependence.

Blacha A., Cardona M., Christensen N.E., Ves S., Overhof H.

The authors have investigated theoretically and experimentally the dependence of the spin-orbit splitting of the edge excitons in CuCl, CuBr, and CuI on volume. The results indicate a large contribution of the change in p(halogen)-d(Cu) hybridization with volume, especially for CuCl.
