We have determined the effect of hydrostatic pressure P on the superconducting transition temperature T/sub c/ of bulk, A15 Nb/sub 3/Si. For 0< or =P< or =20 kbar (2 GPa), T/sub c/ decrease linearly with increasing pressure at the rate partialP/sub c//partialP = -2.67 x 10/sup -5/ K/bar. From an estimate of partialT/sub c//partialP obtained using recent band structure calculations for the density-of-electronic-states change as a function of lattice parameter in Nb/sub 3/Si, we conclude that the pressure dependence of the electron-phonon interaction primarily determines partialT/sub c//partialP.
