P. Bydžovský, D. Denisova, F. Knapp, P. Veselý

AI总结:

本文将DWIA方法推广到中重超核电生过程,考察K介子扭曲与运动学影响,揭示超核激发谱对ΛN有效相互作用的敏感性,并给出208ΛTl电生激发谱的实验预言。

摘要:

先前用于较轻(p壳和sd壳)系统超核电生截面计算的DWIA形式体系,被用于研究较重的靶核,如$^{52}$Cr和$^{208}$Pb上的电生过程。首先重新考察了K介子扭曲效应和运动学的影响,然后结合不同形式的$Λ$N有效相互作用、基本振幅和运动学,讨论了重靶核的结果。研究表明,超核激发谱对不同形式的$Λ$N有效相互作用表现出明显的敏感性。还给出了在Jefferson Lab正在准备的E12-20-013实验运动学条件下,$^{208}_{~~Λ}$Tl电生激发谱的预言。

英文摘要:

The DWIA formalism for computing the cross sections in electroproduction of hypernuclei used before for lighter (p-shell and sd-shell) systems is utilized in studying electroproduction on heavier targets such as $^{52}$Cr, and $^{208}$Pb. First, the effects from kaon distortion and kinematics are re-examined and then results for the heavy targets are discussed in view of various forms of the $Λ$N effective interaction, the elementary amplitude, and kinematics. Apparent sensitivity of the hypernucleus excitation spectra to various forms of the $Λ$N effective interaction is shown. Predictions of the excitation spectrum in electroproduction of $^{208}_{~~Λ}$Tl are also given in kinematics of the experiment E12-20-013 in preparation at Jefferson Lab.
