We have measured some simple matrix elements for pseudoscalar and vector mesons made of Wilson valence quarks and staggered sea quarks at β=5.6 at sea quark masses amq=0.01 and 0.025. Our measurements include the decay constants of pseudoscalars (including fD), the wave function at the origin (or decay constant) of vector mesons, and the calculation of quark masses from current algebra. The effects of sea quarks on the simulations are small. We make comparisons to quenched simulations at similar values of the lattice spacing (1/a≃2 GeV).
