Properties of the Alpha Decay Chain Nuclei of ³¹⁰126, ²⁹²120 and ²⁹⁸114

The properties of the α decay nuclei of ³¹⁰126, ²⁹²120 and ²⁹⁸114 are investigated in the deformed relativistic mean-field model. The nuclear properties are investigated with the TMA and NL-Z2 parameter sets, and compared with Moller’s result At. Data Nucl. Data Tables 59 (1995) 185. The results show that the α decay energy increases systematically with the increasing proton number. Meanwhile, the α decay energy has a minimum value at the point of shell closure. It is also found that of the three nuclei, ²⁹²120 is the more likely to be the next doubly magic nucleus.
