论文摘要
我们研究了非排他性核子诱导的杜特隆分裂反应对三核子相互作用的敏感性以及包含光谱中三核力效应的分布。为此，我们使用CD邦恩核子核子相互作用或与2π-交换Tucson-Melbourne三核子力相结合，在许多传入的核子实验室能量上求解了三个核子FADDEEV方程。基于这些溶液，以指定的检测角度以及在该角度集成的光谱的传出核的能量光谱。通过在离传核的能量上以给定的角度整合光谱，则还获得了分解过程中三核力效应的角度分布。与弹性核子 - 脱核散射相反，在较高能量下，遇到了显着的三核力效应，用于在横截面的最小值周围散射角度，因为仅发现中等效应，并且仅限于向前角度。本研究的结果表明，当对完成贡献完整的几何形状进行平均时，在不完整的光谱中发现了针对某些特定完整分裂构型的大型三核力效应大大降低。
We investigate the sensitivity of the non-exclusive nucleon induced deuteron breakup reaction to the three-nucleon interaction and distributions of three-nucleon force effects in inclusive spectra. To this end we solve the three-nucleon Faddeev equation at a number of incoming nucleon laboratory energies using the CD Bonn nucleon-nucleon interaction alone or combined with the 2π-exchange Tucson-Melbourne three-nucleon force. Based on these solutions energy spectra of an outgoing nucleon, at a specified detection angle as well as spectra integrated over that angle, are calculated. By integrating the spectra at a given angle over the energy of the outgoing nucleon the angular distributions of three-nucleon force effects in the breakup process are additionally obtained. Contrary to elastic nucleon-deuteron scattering, where at higher energies significant three-nucleon force effects were encountered for scattering angles around the minimum of the cross section, for the breakup process only moderate effects are found and they are restricted to forward angles. Results of the present investigation show that the large three-nucleon force effects found for some specific complete breakup configurations are reduced substantially in the incomplete spectra when averaging over contributing complete geometries is performed.
