N1 - Funding Information:
To study this question we have considere'd a system of two coupled energy bands, one of which is infinitesimally narrow, and calculated the energy spectrum and the electron-phonon interaction in the tight-binding approximation (TBA). The calculations were applied for V3Si, and the two particular atomic wave-functions chosen were vanadium 3d a and 81 orbitals. The tight-binding parameters we used were \[3\]: * Work supported by a grant from the National Council for Research and Development, Israel and KfK (Kernforschungszentrum, Karlsruhe, Germany).

N2 - The parameter N(0)I2, where N(0) is the density of states at the Fermi energy and I2 is the electron-phonon coupling constant, is calculated in a model which gives rise to high N(0) due to localization. The calculation is based on the localized description of superconductivity formulated by Appel and Kohn. It is found that although N(0) can become high, N(0)I2 can nevertheless be very low.
