标题： Ab initio calculation of the 4He(e,e'd)d reaction

摘要： 双体打靶反应 4He(e,e'd)d 在不同的动量转移下进行了计算。 初始态和末态中都微观地考虑了四核子动力学。 作为核子-核子相互作用，使用了中心势 MT-I/III。 计算显示，由于末态相互作用，符合截面显著减小。 尽管如此，理论结果在较低动量转移时对实验截面有明显的高估。 与其他较不完整的计算进行比较表明，考虑更现实的基态可能不足以与实验良好一致，而更现实的末态相互作用可能起着关键作用。 显示英文摘要

摘要： The two-body knock-out reaction 4He(e,e'd)d is calculated at various momentum transfers. The full four-nucleon dynamics is taken into account microscopically both in the initial and the final states. As NN interaction the central MT-I/III potential is used. The calculation shows a strong reduction of the coincidence cross section due to the final state interaction. Nonetheless the theoretical results exhibit a considerable overestimation of the experimental cross section at lower momentum transfer. Comparisons with other, less complete, calculations suggest that consideration of a more realistic ground state might not be sufficient for a good agreement with experiment, rather a more realistic final state interaction could play an essential role.
