| Abstract: | 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. |
| Keywords: | New nuclide Optimization method Decay of a radioactive series Half life |
