Query: Low Energy Neutron Production by Inverse-beta decay in Metallic Hydride
  Surfaces   It has been recently argued that inverse-beta nuclear transmutations might
occur at an impressively high rate in a thin layer at the metallic hydride
surface under specific conditions. In this note we present a calculation of the
transmutation rate which shows that there is little room for such a remarkable
effect.
