轻核从头算无芯组态相互作用计算中转动带的出现

Emergence of rotational bands in ab initio no-core configuration interaction calculations of light nuclei

M. A. Caprio, P. Maris, J. P. Vary

摘要:

在无核组态相互作用(NCCI)计算中,我们观察到了奇质量Be同位素(7<=A<=13)在JISP 16核子-核子相互作用下的转动带的出现,这一点可以通过激发能、四极矩和E2跃迁的转动模式得到证实.计算结果表明,利用真实的核子-核子相互作用,在NCCI计算中可以得到较好的转动结构。

英文摘要:

The emergence of rotational bands is observed in no-core configuration interaction (NCCI) calculations for the odd-mass Be isotopes (7<=A<=13) with the JISP16 nucleon-nucleon interaction, as evidenced by rotational patterns for excitation energies, quadrupole moments, and E2 transitions. Yrast and low-lying excited bands are found. The results demonstrate the possibility of well-developed rotational structure in NCCI calculations using a realistic nucleon-nucleon interaction.
