The simulations are performed in the quenched approximation at beta=6.0 and beta=6.2 using a non-perturbatively improved clover action. The slope of the Isgur Wise function and |Vcb| are extracted from the form factors.LaTeX. 6 PostScript figures. Contribution to LATTICE99(Heavy Quarks)High Energy Physics - Latticetext
