LOW-INTENSITY CONVERSION LINES IN TWO WEAKLY DEFORMED NUCLEI
Technical Report

OSTI ID:4243270
The electron spectrum of Sm/sup 151/ was measured with a lens spectrometer and its gamma-ray spectrum with a scintillation spectrometer. The L- conversion coefficient of the 21.7 sintering time 0.3 kev de-excitation of the first exeited state of Eu/sup 151/ is 20 sintering time 4, with alpha /sub L// alpha /sub M+N/ = 2.2 PP 0.4 and alpha /sub M// alpha /sub N/ = 2.2 sintering time 0.2 indicating Ml multipolarity. The low intensity of the conversion electrons relative to the continuous beta spectrum of end point 75.9 sintering time 0.6 kev implies the existence of a weak beta transition whose end point is 54.2 sintering time 0.7 kev. The beta branching ratio 54.2-kev transitions/ 75.9 kev transitions is 1.7/100. (auth)
