  Low energy nuclear transmutations have been reported in experimental chemical
electrolytic cells employing metallic hydride electrodes. Assuming that the
nuclear transmutations are induced by ultra-low momentum neutron absorption,
the expected chemical cell nuclear abundances are discussed on the basis of a
neutron optical potential model. The theoretical results are in satisfactory
agreement with available experimental chemical cell data. Some implications of
these laboratory nuclear transmutations for r- s-process models of the neutron
induced solar system and galactic nuclear abundance are briefly explored.
