Half-life and α-ray energy of146Sm

  • Published:
Zeitschrift für Physik A Atomic Nuclei

Abstract

Up-to-date α-decay data of the double-even,N=84 isotones are presented, including the presently remeasured values for146Sm. For this nuclide a half-life,T 1/2 =1.031 (45) ×108 y, and α-ray energy, Eα=2455(4) keV, were measured. The significance of these data for the subshell closure atZ=64 observed in α-decay is discussed.
