标题： Spectroscopy and intruder configurations of $^{33}$Mg and $^{31}$Ne studied with antisymmetrized molecular dynamics

摘要： 激发谱和中子单粒子构型的$^{33}$Mg 和$^{31}$Ne 通过结合反对称分子动力学和生成坐标方法进行研究。 结果显示，这两个核都具有强变形的$3/2^-$基态，具有$3p2h$构型。 激发谱在 Nilsson 模型的基础上得到了定性的理解，计算表明在小激发能下存在不同侵入构型的共存。 计算得到的$^{31}$Ne 的一个中子分离能相当小（$S_n=250$keV），意味着具有强变形核心的 p 波单中子晕。 显示英文摘要

摘要： Excitation spectra and neutron single particle configurations of $^{33}$Mg and $^{31}$Ne are investigated by using antisymmetrized molecular dynamics combined with generator coordinate method. It is shown that both nuclei have strongly deformed $3/2^-$ ground state with a $3p2h$ configuration. The excitation spectra are qualitatively understood in terms of the Nilsson model and the calculation has shown the coexistence of different intruder configurations within small excitation energy. The calculated one neutron separation energy of $^{31}$Ne is rather small ($S_n=250$ keV) and implies a p-wave one neutron halo with a strongly deformed core.
