摘要:

通过研究复能平面内多步壳层模型中的三中子一质子激发,评价了未束缚核$^{12}$ Li。发现该体系的基态由反束缚$2^-$态组成。在低能量下发现了一些窄态,这是由$^{11}$ Li中的共振耦合到接近阈值的连续态引起的。

英文摘要:

The unbound nucleus $^{12}$Li is evaluated by studying three-neutron one-proton excitations within the multistep shell model in the complex energy plane. It is found that the ground state of this system consists of an antibound $2^-$ state. A number of narrow states at low energy are found which ensue from the coupling of resonances in $^{11}$Li to continuum states close to threshold.
