用复能面多步壳模型方法计算~（12）Li的能谱
Calculation of the spectrum of 12Li by using the multistep shell model method in the complex energy plane
摘要：
在复能平面上用多步壳层模型计算了未束缚核$^{12}$ Li的能谱，假定能谱由$^9$ Li核外的三个中子的运动决定.发现该体系的基态由反束缚$1/2^+$态组成，只有反束缚态和$1/2^-$、$5/2^+$激发态才是物理意义上的共振态.
英文摘要：
The unbound nucleus $^{12}$Li is evaluated by using the multistep shell model in the complex energy plane assuming that the spectrum is determined by the motion of three neutrons outside the $^9$Li core. It is found that the ground state of this system consists of an antibound $1/2^+$ state and that only this and a $1/2^-$ and a $5/2^+$ excited states are physically meaningful resonances.
