In this talk we present the results obtained from a study of O(2000) (quenched) lattice configuration from the APE collaboration, at 6.0 ⩽ Q ⩽ 6.4, using both the Wilson and the SW-Clover fermion action. We determine the light hadronic spectrum and the meson decay constants. For the light-light systems we find an agreement with the experimental data of ∼ 5∼ for mesonic masses and ∼ 10∼-15∼ for baryonic masses and pseudoscalar decay constants; a larger deviation is present for the vector decay constants. For the heavy-light decay constants we find fD1 = 237 ±16MeV, fD = 221 ±17MeV (fD1/fD = 1.07(4)), fB1 = 205±35 MeV, fB = 180±32 McV (fB1/fB = 1.14(8)), in good agreement with previous estimates.
