Because of the great interference of The U.S. Department of Energy's Office of Scientific and Technical Information The Eu-152 radionuclide solution in 4 M nitric acid for the comparison was prepared by the decay-scheme parameters 0.29 11.

] 152 Eu : Half-life: Fermion, 63p 89n: 13.537 y: Spin 3 Parity -1: Show Decay Modes: Show Ultimate Decay Products 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). The primary decay mode before the most abundant stable isotope, 153 Eu, is electron capture, and the primary mode after is beta decay. 151 Eu is the beta decay product of samarium-151, but since this has a long decay half-life and short mean time to neutron absorption, most 151 Sm instead ends up as 152 Sm. 152 Eu (half-life 13.516 years) and 154 Eu (half-life 8.593 years) cannot be beta decay products because 152 Sm and 154 Sm are non-radioactive, but 154 Eu is the only long-lived "shielded" nuclide, other than 134 Cs, to have a fission yield of more than 2.5 parts per million fissions. Europium 152 and Europium 154. This excellent spectrum was kindly provided by Christoph Denk, an uncommon isotope to get hold of, Eu152 and Eu154 is a man made isotope, and has a half life of 13.5 years. This Spectrum was recorded with GS-1100A and a Harshaw Scintillation Detector. There are no products to list in this category.

About 130 γ-ray transitions are known to follow the decay, with intensities above 10А5 photons per parent decay. A recent evaluation of the 152Eu decay scheme 152Eu disintegrates with a half-life of 13.5 years emitting a multitude of high energy photons.
