Scientific paper

First results are obtained for B mesons using a heavy propagator calculated using NRQCD, and a light Wilson propagator. Results from 13 quenched configurations of size 16^3 x 48 at \beta = 6.0 give a value for f_{B} of less than 200 Mev and a B^{*}-B splitting of 32(8) MeV. Superior signal/noise behaviour is observed over static propagators on the same configurations. No extrapolation to the b mass for the heavy quark is required.
