Previously described work (C, 1984) is extended on calcns. of deformation potential of the valence band edge of CuBr by using self-consistent, relativistic linear combination of muffin-tin orbital method. From total energy calcns. for varying vol., the calcd. equil. lattice const. is 1.9\% below the exptl. value. The calcd. bulk modulus is in agreement with the exptl. data of R. C. Hanson et al., (1972).
