Description

We report the first Knight-shift studies of the heavy-fermion superconducting state. In 5 kOe the Knight shift of muons in superconducting U/sub 1-//sub x/Th/sub x/Be/sub 13/ remains near the normal-state value for x = 0.033, but show an unexpected strong decrease for x = 0. If the pairing is of odd parity, this decrease suggests that the anisotropic order parameter is pinned to the lattice. The qualitatively different behavior for x = 0.033 reflects either spin-orbit scattering by Th doping or a change of pairing symmetry
