在{sup 96}Zr中,3{sub 1}{sup{-}}水平的半衰期为{ital T}{sub 1/2}=50(7) ps。推导出的{数字B}({数字E}3)速率为65(10)w .u,使得这个3{sub 1}{sup {-}}{r箭头}0{sub 1}{sup +}跃迁是已知的最快的跃迁。用随机相位近似和变形壳模型解释的结果表明{sup 96}Zr附近的八极不稳定性。
A half-life of {ital T}{sub 1/2}=50(7) ps was measured for the 3{sub 1}{sup {minus}} level in {sup 96}Zr. The deduced {ital B}({ital E}3) rate of 65(10) W.u. makes this 3{sub 1}{sup {minus}}{r arrow}0{sub 1}{sup +} transition the fastest known. The results interpreted in terms of the random phase approximation and a deformed shell model suggest octupole instability around {sup 96}Zr.
