Abstract

Properties of wide superconducting tin films in the resistive current state with phase slippage have been studied experimentally. We have observed a region of excess conductivity on the current-voltage characteristics of the samples. Experimental results were discussed in view of the theory establishing the relationship between an interference term of the total current and excess current in weak superconductors. We derived the equation to evaluate the inelastic scattering time of superconductor τ E using the excess current of wide films with phase slippage. Our τ E values are in a good agreement with those obtained by other methods.
