标题： Z=110--111 Elements and the Stability of Heavy and Superheavy Elements

摘要： 最近发现的Z=110--111同位素表明有(1)一种单极-单极相互作用，这在Nilsson--Strutinsky质量系统学中并未明确出现，以及(2)$SU(2)$和$SU(3)$动态对称性之间的竞争，这种竞争已在此区域被预测。我们的计算表明，这些新同位素接近球形，可能代表一个真正的超重核岛，但因这些新的物理效应而向下偏移中子数。 显示英文摘要

摘要： The recent discovery of isotopes with Z=110--111 suggests evidence for (1) a monopole--monopole interaction that does not appear explicitly in Nilsson--Strutinsky mass systematics, and (2) a competition between $SU(2)$ and $SU(3)$ dynamical symmetries that has been predicted for this region. Our calculations suggest that these new isotopes are near spherical, and may represent a true island of superheavy nuclei, but shifted downward in neutron number by these new physical effects.
