Abstract

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.
