Abstract
The enhancement of the pressure dependence of the electron-phonon matrix element due to ion core orthogonality constraints is shown to be an important factor in understanding the observed increase in the superconducting transition temperature with pressure in Ba. We find no evidence for Wittig's recent suggestion of the crucial role played by 4f hybridization.
