Abstract
The internal conversion subshell intensities of the (21.529±0.014) keV transition in151Eu and the (22.494±0.011) keV transition in149Sm have been determined in a high resolution investigation using a double-focussing iron-core spectrometer. The subshell ratios yielded unambiguousM1+E2 multipole mixtures for both transitions. δ2(E2/M1) for the 21.53 keV transition was determined to be (8.8±0.7)·10−4 and for the 22.49 keV transition to be (5.5±1.2)·10−3.
