论文摘要
具有电荷数Z = 101-109的重核中的弱衰变在微观形式主义中研究了基于变形的自洽的Skyrme Hartree Hartree-fock平均场计算与配对相关性。将β+衰变和电子捕获的半衰期与从现象学配方获得的α-末期半衰期进行了比较。可以考虑在冷和热融合蒸发通道的边界生产的MD，NO，LR，RF，DB，SG，BH，HS和MT的转移剂同位素。确定了几种同位素，其beta+/ec-和alpha-decay的半衰期是可比的。这些衰变模式之间的竞争为通向稳定岛的新途径开辟了可能性。
Weak decays in heavy nuclei with charge numbers Z=101-109 are studied within a microscopic formalism based on deformed self-consistent Skyrme Hartree-Fock mean-field calculations with pairing correlations. The half-lives of beta+ decay and electron capture are compared with alpha-decay half-lives obtained from phenomenological formulas. Transfermium isotopes of Md, No, Lr, Rf, Db, Sg, Bh, Hs, and Mt that can be produced in the frontier of cold and hot fusion-evaporation channels are considered. Several isotopes are identified whose beta+/EC- and alpha-decay half-lives are comparable. The competition between these decay modes opens the possibility of new pathways towards the islands of stability.
