Upper critical field and its anisotropy have been measured on two very short wavelength Mo-Ni heterostructures of different degrees of perfection, lambda equals 13. 8 Angstrom disordered structure and lambda equals 16. 6 Angstrom (layered structure). In both cases the parallel critical field has an unexpected temperature dependence, a large and temperature dependent anisotropy, and over 60% enhancement over the Clogston-Chandrasekhar limit. Data are fit to the Werthamer-Helfand-Hohenberg theory and the spin-orbit scattering times are found to be 1. 79 multiplied by 10** minus **1**3 sec and 2 multiplied by 10** minus **1**3 sec, respectively.
