Abstract

We present scanning tunneling spectroscopy measurements on the heavy-fermion superconductor PrOs4Sb12. Our results show that the superconducting gap opens over a large part of the Fermi surface. The deviations from isotropic BCS s-wave behavior are discussed in terms of a finite distribution of values of the superconducting gap.
