Abstract

An isomer shift has been observed in the Mössbauer study of the 121.8-keV (2+0+) transition in Sm152. A value of (ΔR2R2)20=(10±3)×104 is deduced, based on isotope shift data for Sm152 and Sm154. This value disagrees with present theoretical prediction. In particular, the influence of the β band in Sm152 can only account for about 20% of the observed stretching.
