Abstract
We report the observation of a T2 temperature dependence of the magnetic field penetration depth in UBe13 at low temperatures. We show that this behavior is consistent with an anisotropic gap function for an axial P-wave state. Our results further show that the Landau parameter Fls appears to be small.
