Non-factorized calculation of the process 3He(e,e'p)pn at medium energies

M. Alvioli C. Ciofi degli Atti, L. P. Kaptari

摘要:

在广义程函近似下,采用非因式分解和无参数方法,基于对应于$AV18$相互作用的实际少体波函数,计算了三体分裂过程3 He(e,e 'p)pn的横纵不对称性A_{TL}和截面.计算结果与最近的JLab实验数据符合得很好,并表明在丢失动量300 < p_m < 600 MeV/c和去除能E_m > p_m^2/4m_N的区域内,被撞击质子的末态相互作用(FSI)主要由单核子再散射所控制,这与核子-核子关联的预言相一致.

英文摘要:

The cross section and the transverse-longitudinal asymmetry A_{TL} of the three-body-break-up (3BBU) process 3He(e,e'p)pn have been calculated by a non-factorized and parameter-free approach based upon realistic few-body wave functions corresponding to the $AV18$ interaction, treating the rescattering of the struck nucleon within a generalized eikonal approximation. The results of calculations exhibit a good agreement with recent JLab experimental data and show that the Final State Interaction (FSI) of the struck proton in the region of missing momentum 300 < p_m < 600 MeV/c and removal energy E_m > p_m^2/4m_N is dominated by single nucleon rescattering, in agreement with nucleon-nucleon correlation predictions.
