Abstract: We have performed a study of the behavior of superconductors under light illumination. In one of the experiments the acoustical coupling of two thin superconducting films forming a tunnel junction was measured. The experiment was performed by photo-exciting quasi-particles in on film and studying the resulting charge in the energy gap. A detailed comparison shows agreement of the experimental results with Little's theory of the acoustical coupling of solids. In addition, the results indicate that the acoustic coupling of a thin lead film to the helium bath is much stronger than the underlying tin film and substrate.

In another experiment we have measured directly for the first time the relaxation time of Tau of the superconducting energy gap. We show that near the superconducting transition temperature Tau(sub c) the relaxation time diverges as predicted by several authors. It is observed for the first time that near Tau(sub c) the equilibrium energy gap does not obey the BCS temperature dependence, a result which is attributed to inhomogeneous in the films.
