摘　　要：根据合成２３９Ｐａ实验的特定条件，利用递次衰变关系首次确定了丰中子新核素２３９Ｐａ的半衰期。The numerical methods used in analysing the experimental decay data of synthesizing a new heavy neutron rich isotope 239 Pa are studied,and its half life is obtained by analysing the decays of a radioactive series for the first time.The obtained results reproduce the experimental decay curve well and support the conclusion for the identification of 239 Pa.
