Let M be a complete geometrically finite manifold of bounded negative curvature, infinite volume and dimension at least 3. We give both a lower bound for the bottom of the spectrum of M and an upper bound for the number of the small eigenvalues of M . These bounds only depend on the dimension, curvature bounds and the volume of the one-neighborhood of the convex core. 1
