AI 中文摘要
半幻核¹⁴C位于N=8反转岛上方，存在低能侵入态及相关形变的可能性。通过从头算无芯组态相互作用计算，阐明¹⁴C中侵入结构、四极形变与Elliott SU(3)对称性的作用，结果还凸显了正常态与侵入态混合对前两个2⁺态E2跃迁强度的影响。
英文摘要
The semimagic nucleus $^{14}\mathrm{C}$ lies just above the $N=8$ island of inversion, raising the possibility of low-lying intruder states and associated deformation. Through ab initio no-core configuration interaction calculations, we shed light on the role of intruder structure, quadrupole deformation, and Elliott SU(3) symmetry in $^{14}\mathrm{C}$. The results also highlight the influence of mixing between normal and intruder states on the strengths of the $E2$ transitions from the first two $2^+$ states.
