Abstract
The observation of the magnetic field splitting of the quasiparticle states in thin superconducting films does make it possible to determine the size of spin-orbit interactions via tunneling experiments. We calculate the tunneling density of states of such films in the presence of spin-orbit interactions and demonstrate that the tunneling conductance between two films of identical material in a parallel field should be an especially sensitive function of spin-orbit scattering. Numerical results for the tunneling density of states as well as for the tunneling conductance as function of spin-orbit scattering rate are presented.
