Abstract
We have obtained channeling-radiation spectra for both electrons and p ositrons incident along the major planes of LIH and LID crystals. Anal ysis of the data yields two significant results: (1) the thermal-vibra tion amplitude of LiD is smaller than that of LiH, as one would expect for this isotopic effect, but in contradiction with tabulated values; and (2) a tunneling transition was observed for 54-MeV electron chann eling along the (111) planes of both LiH and LiD.
