Abstract

We report the observation of a

T^{2}

temperature dependence of the magnetic field penetration depth in U

{Be}_{13}

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

F_{l}^{s}

appears to be small.
