论文摘要
在合成Z = 119和Z = 120的超脱核核之后，系统地研究了α-和β+/EC-DECAID模式之间的抗核之间的竞争。一种基于形成的Hartree固定量捕获与天空捕获的型号，与Sky-Spreeliations+配对相关的相对型号，该方法基于Z = 119和Z = 120。而alpha-decay是从现有现象学表达中估计的。结果表明，在大多数情况下，alpha-decay是主要的衰减模式，但是在半衰期相当的情况下可以确定有趣的实例，这为该区域的新途径开放了新的途径。
The competition between alpha- and beta+/EC-decay modes is studied systematically in nuclei along the alpha-decay chains following the synthesis of superheavy nuclei with Z = 119 and Z = 120. A microscopic approach based on deformed self-consistent Hartree-Fock mean-field calculations with Skyrme forces and pairing correlations is used to describe the beta+ and electron capture weak decays, whereas the alpha-decay is estimated from existing phenomenological expressions. It is shown that alpha-decay is in most cases the dominant decay mode, but interesting instances are identified where the half-lives are comparable, opening the possibility of new pathways towards more neutron-rich nuclei in this region.
