Abstract: Using Heavy Quark Effective Theory with non-perturbatively determinedparameters in a quenched lattice calculation, we evaluate the splittingsbetween the ground state and the first two radially excited states of the $B s$system at static order. We also determine the splitting between first excitedand ground state, and between the $B s^*$ and $B s$ ground states to order$1-m b$. The Generalized Eigenvalue Problem and the use of all-to-allpropagators are important ingredients of our approach.
