We investigate the perturbation in the tunneling current caused by nonadiabatic mechanical motion in a mesoscopic tunnel junction. A theory introduced by Caroli et al. is used to evaluate second-order self-energy corrections for this nonequilibrium situation lacking translational invariance. Inelastic signatures of the mechanical degrees of freedom are found in the current-voltage I(V) characteristics. These give rise to sharp features in the derivative spectrum, d2I/dV2.
