摘要

在准自由散射运动学附近，给出了一组三体$^{2}$H($d$，$dp$)$n$在160 MeV氘核束能量下的分裂反应的微分截面。实验是在荷兰格罗宁根的KVI使用BINA探测器进行的。将截面数据归一化为$^{2}$H($d$，$d$)$^{2}$H弹性散射截面。这些数据与最近的单散射近似(SSA)计算的氘核-氘核碰撞中三团破碎的结果进行了比较。将SSA预测与实验数据相比较表明，SSA提供了正确的截面数据数量级。所研究的能量可能太低，无法满足SSA假设，从而阻碍了描述的更好准确性。

Three-body breakup in deuteron-deuteron collisions at 160 MeV including quasifree scattering

A set of differential cross section of the three-body $^{2}$H($d$,$dp$)$n$ breakup reaction at 160 MeV deuteron beam energy are presented for 147 kinematically complete configurations near the quasi-free scattering kinematics. The experiment was performed at KVI in Groningen, the Netherlands using the BINA detector. The cross-section data have been normalized to the $^{2}$H($d$,$d$)$^{2}$H elastic scattering cross section. The data are compared to the recent single-scattering approximation (SSA) calculations for three-cluster breakup in deuteron-deuteron collisions. Confronting the SSA predictions with the experimental data shows that SSA provides the correct order of magnitude of the cross-section data. The studied energy is probably too low to meet the SSA assumptions which prevents better accuracy of the description.
