Electric multipole response of the halo nucleus $^6$He

Jagjit Singh, L. Fortunato, A. Vitturi, R. Chatterjee

摘要:

本文利用简单配对接触-δ相互作用耦合$^5$ He的未束缚spd波,研究了弱束缚核$^6$ He中不同连续分量的作用。我们以前的研究结果在一个模型空间只包含p-波,显示集体性质的基态,并允许计算的电四极跃迁。我们扩展了这个简单的模型,也包括SD-连续中子状态,我们调查的电偶极,偶极和八极响应的系统过渡到连续,讨论不同的配置的贡献。

英文摘要:

The role of different continuum components in the weakly-bound nucleus $^6$He is studied by coupling unbound spd-waves of $^5$He by means of simple pairing contact-delta interaction. The results of our previous investigations in a model space containing only p-waves, showed the collective nature of the ground state and allowed the calculation of the electric quadrupole transitions. We extend this simple model by including also sd-continuum neutron states and we investigate the electric monopole, dipole and octupole response of the system for transitions to the continuum, discussing the contribution of different configurations.
