通过双核子转移过程中中间核能谱的照相实现配对增强

Pairing enhancement through the photography of the intermediate nucleus spectrum in a two-nucleon transfer process

G. Singh

AI总结:

本文从变化的配对场和不同连续谱视角,分析了双中子转移反应中通过中间核连续谱实现的配对增强,以^6He和^22C为例,揭示了连续谱关联对配对增强延伸的关键作用。

摘要:

在通过双中子转移反应由核A形成(A+2)核的过程中,众多可能反应通道的相长干涉有利于通过中间(A+1)核的连续谱实现显著的配对增强[Phys. Lett. B 834 137413 (2022)]。我从更普遍的角度分析了这一情况,即从变化的配对场和导致(A+2)核形成的不同连续谱的观点出发。我考虑了^6He和^22C,分别描述为在^5He和^21C的轨道中容纳两个中子。不同可能的情况表明,连续谱关联对于系统中观察到的配对增强的延伸是极其关键的。

英文摘要:

While forming an ($A$+2) nucleus from a nucleus $A$ via a two-neutron transfer reaction, the constructive interference of the many possible reaction channels favors significant pairing enhancement through the continuum of the intermediate ($A$+1) nucleus [Phys. Lett. B \textbf{834} 137413 (2022)]. I analyse this situation in more generality, from the point of view of a varying pairing field and different continua leading to the formation of ($A$+2) nucleus. I consider $^6$He and $^{22}$C, described as housing two-neutrons in orbitals of $^5$He and $^{21}$C, respectively. The different possible situations manifest that the continuum correlations are extremely crucial to the extension of the pairing enhancement observed in the system.
