Abstract
We present results of our quenched study of the B meson decay constant obtained with a parallel set of simulations with the Wilson and Clove r actions at beta=5.9, 6.1 and 6.3. Systematic errors associated with the large b-quark mass are analyzed within the Fermilab non-relativist ic formalism. As our best estimate in the continuum limit we obtain f( B)=163+/-16 MeV and f(Bs)=175+/-18 MeV with the Clover action.
