给出了双偶、N = 84同中子素最新的α衰变数据，包括对¹⁴⁶Sm目前重新测量的值。对于这种核素，测量得到半衰期T₁/₂ = 1.031(45)×10⁸年，α射线能量Eα = 2455(4) keV。讨论了这些数据对于在α衰变中观察到的Z = 64处亚壳层闭合的意义。
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,T1/2 =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.
