摘要:

在氘实验室能量为110、133和180 MeV时测量了反应$p(d,^3{\rm He})γ$的微分截面。这些数据是用测量出射$^3$ He和光子的符合装置获得的。的数据进行了比较,包括所有可能的介子交换电流和两个和三个核子力的潜力与现代计算。数据清楚地显示出对其中一种模型的偏好,尽管角分布的形状不能由任何提出的模型再现。

英文摘要:

Differential cross sections of the reaction $p(d,^3{\rm He})γ$ have been measured at deuteron laboratory energies of 110, 133 and 180 MeV. The data were obtained with a coincidence setup measuring both the outgoing $^3$He and the photon. The data are compared with modern calculations including all possible meson-exchange currents and two- and three- nucleon forces in the potential. The data clearly show a preference for one of the models, although the shape of the angular distribution cannot be reproduced by any of the presented models.
