~(213)Bi有2种衰变方式:β~-和α衰变,其衰变分支比分别是(97.91±0.03)%和(2.09±0.03)%。本文运用限权平均法(LWM)处理实验数据,给出了全套核衰变数据。评价推荐的半衰期为
~ (213) Bi has two decay modes: β ~ - and α decay, the decay branch ratio is (97.91 ± 0.03)% and (2.09 ± 0.03)% respectively. In this paper, LWM is used to process the experimental data and a complete set of nuclear decay data is given. The recommended half-life is
