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.
