A low energy beta group- with an end point at 417 keV was found, Abstract. The decay of mass-spectrometrically enriched 152 Eu has been studied using a Siegbahn-Slätis beta ray spectrometer, a scintillation spectrometer and a gamma- gamma coincidence device. From the analysis of the beta spectrum αK of the 344 keV gamma radiation is found to be 0.033 ± 0.001. A low energy beta group- with an end point at 417 keV Recommended Nuclear Decay Data Eu-152. Decay Mode: EC, β ¯, (β +) Half-Life: (4943 ± 5) d 1818.919 ± 0.689 (keV) Strong Gamma-rays from Decay of Eu-152 (Compiled from ENSDF as of March 2011) [ Intensities before May 23th of 2013 were values when total intensity of the decay mode was 100 (%) and a branching ratio of each decay mode was not multiplied. ] This element also has 17 meta states, with the most stable being 150m Eu (t 1/2 12.8 hours), 152m1 Eu (t 1/2 9.3116 hours) and 152m2 Eu (t 1/2 96 minutes).
