Abstract
We show that the tunnel coupling between semiclassical states localize d in different minima of a smooth random potential increases when a ma gnetic field is applied. We illustrate the increase of coupling by a m odel calculation of tunneling through a saddle point separating two ad jacent lakes. The effect of the field on coupling constants leads to a negative magnetoresistance in low-temperature conduction.
