Nuclear mass parabola and its applications
Junlong Tian · Di Yuan · Yunyi Cui · Yun Huang · Ning Wang
We propose a method to extract the properties of the isobaric mass parabola based on the total double decay energies of isobaric nuclei. Two important parameters of the mass parabola, the location of the most -stable nuclei and the curvature parameter , are obtained for 251 A values based on the total double decay energies of nuclei compiled in AME2016 database.The advantage of this approach is that we can remove the pairing energy term caused by odd-even variation, and the mass excess of the most stable nuclide for mass number in the performance process, which are used in the mass parabolic fitting method. The Coulomb energy coefficient MeV is determined by the mass difference relation of mirror nuclei, and the symmetry energy coefficient is also studied by the relation .
