中能~ 3 He(e,e 'p)~ 2 H过程的非因式计算

Non-factorized calculation of the process 3He(e,e'p)2H at medium energies

摘要:

本文用非因式分解和无参数的方法分析了排它过程~ 3 He(e,e 'p)~ 2 H,该方法基于对应于$AV18$相互作用的实际少体波函数,并在广义程函近似下处理了碰撞核子的再散射。我们的计算结果,与最近的JLab实验数据相比,表明左右不对称性表现出明显的依赖于最终状态的相互作用,证明了分解近似在“负”和大(> 300 MeV/c)值的丢失的动量。

英文摘要:

The exclusive process 3He(e,e'p)2H has been analyzed by a non-factorized and parameter-free approach based upon realistic few-body wave functions corresponding to the $AV18$ interaction and treating the rescattering of the struck nucleon within a generalized eikonal approximation. The results of our calculations, compared with recent JLab experimental data, show that the left-right asymmetry exhibits a clear dependence upon the final state interaction demonstrating the breaking down of the factorization approximation at "negative" and large (> 300 MeV/c) values of the missing momentum.
