AI总结:

本文提出一个包含核心集体四极模式耦合的理论框架,同时处理14C中束缚态配对振动和连续谱巨配对振动,并成功应用于双中子转移反应布居的激发谱。

摘要:

我们提出了一个理论框架,用于处理Jπ = 0+配对添加模式的完整激发谱,包括众所周知的低激发束缚态配对振动,以及与预言中位于连续谱中的巨配对振动同等对待。我们的形式体系包含了与核心低能集体四极模式的耦合,从而同时考虑了单粒子自能效应和由声子交换诱导的配对相互作用。该理论被应用于14C的激发谱,该激发谱最近通过双中子转移反应被布居。

英文摘要:

We present a theoretical framework for treating the full excitation spectrum of Jπ = 0+ pair addition modes, including the well-known low-lying and bound Pairing Vibration on par with the predicted Giant Pairing Vibration lying in the continuum. Our formalism includes the coupling to low-energy collective quadrupole modes of the core, in such a way that both single-particle self-energy effects and the pairing interaction induced by phonon exchange are accounted for. The theory is applied to the case of the excitation spectrum of 14C, recently populated by two-neutron transfer reactions.
