The indication for the α decay of 151Eu (Qα=1.964 MeV) with the half-life yr has been observed for the first time with the help of a low background CaF2(Eu) crystal scintillator (mass of 370 g) in measurement at the Gran Sasso National Laboratories of the INFN during 7426 h. In a conservative approach the lower limit on the half-life of 151Eu has been established as yr at 68% C.L.

Abstract

The indication for the α decay of 151Eu (Qα=1.964 MeV) with the half-life yr has been observed for the first time with the help of a low background CaF2(Eu) crystal scintillator (mass of 370 g) in measurement at the Gran Sasso National Laboratories of the INFN during 7426 h. In a conservative approach the lower limit on the half-life of 151Eu has been established as yr at 68% C.L.
