Abstract

The differential cross sections for the $^2$H(p,pp)n reaction have been measured for 84 angular configurations of the outgoing protons in the range of polar angles from 13 to 33 degrees with a proton beam of 108 MeV. Data have been collected in the Cyclotron Center Bronowice (CCB) at the Institute of Nuclear Physics PAS in Cracow, using the BINA detector setup. Analysis leading to determination of the breakup cross section values is described. Absolute normalization is obtained by normalization to the simultaneously measured $^2$H(p,d)p scattering events.Experimental results are compared to the state-of-the-art theoretical calculations. Global analysis shows significant influence of the Coulomb interaction and small effects of three nucleon force in the studied phase space region.
108 兆电子伏质子诱导氘核破裂中三个核子系统动力学的实验研究
用 108 兆电子伏的质子束测量了出射质子在 13 至 33 度极角范围内的 84 个角度构型的 $^2$H(p,pp)n 反应的微分截面。数据是在克拉科夫核物理研究所(Institute of Nuclear Physics PAS)的布罗诺维采回旋加速器中心(Cyclotron Center Bronowice,CCB)利用 BINA 探测器装置收集的。文中介绍了确定分裂截面值的分析方法。实验结果与最新理论计算结果进行了比较。全局分析表明,在所研究的相空间区域,库仑相互作用的影响很大,而三核力的影响很小。
