Abstract
The electronic band structure of zinc-blende CuCl is computed using a self-consistent, first-principles, all-electron approach. The calculated energy levels agree with photoemission results and support a minimum-direct-gap interpretation of the optical data. Contrary to the indirect model proposed by Rusakov and used by Abrikosov to explain superdiamagnetism and/or high-temperature superconductivity, the calculated band-pressure coefficients do not yield an indirect gap at the pressure where anomalies appear.Keywords
