通过β延迟质子发射鉴定出了在~(40)Ca(~(28)Si,3n)反应中产生的一个具有T_z=-3/2,A=4n+1的核素~(65)Se。观察到其单质子能量为3.70±0.08MeV,实验测定的半衰期为9.6_(-4.1)~(+5.3)ms,它相应于由~(65)Se基态到~(65)As中最低的T=3/2相似态的超允许β跃迁和随后由此态到~(64)Ge基态的质子发射。基于这些结果并结合库仑位移能计算,得到~(65)Se的质量剩余为-33.26±0.25MeV。
A nuclide ~ (65) Se with T_z = -3 / 2 and A = 4n + 1 was generated from the reaction of ~ (40) Ca (~ 28) Si and 3n by β delayed proton emission. The single proton energy was observed to be 3.70 ± 0.08 MeV and the half-life was 9.6 × (-4.1) ~ (+5.3) ms, which corresponds to the lowest T = 3/2 super-allowable β transitions and subsequent proton emission from this state to the ~ (64) Ge ground state. Based on these results, combined with the Coulomb displacement energy calculation, the mass balance of ~ (65) Se was -33.26 ± 0.25 MeV.
