Abstract
We report the first reliable observation of the tiny shifts of energy levels of a nucleus placed between two parallel metallic plates. We ob served the absorption of the 81 keV gamma ray from Cs-133 induced by t he beta-decay of Ba-133 in a BaTiO3 compound. This Mossbauer experime nt was carried out at 4.2 K with the absorber placed between two silic on plates with gold coating. The observed shifts are around 0.95 neV ( equivalent to 0.007 mm/s) for the distance of about 2 mm between the t wo plates.
