Proton-induced scattering of 238U nuclei, with spheroidal deformations at beam energies above 100 MeV, is simulated using an improved quantum molecular dynamics model. The angular distribution of the deflected protons is highly sensitive to the orientation of the symmetrical long axis of the target nuclei with respect to the beam direction. As a result, in reverse kinematic reactions, an orientation dichroism effect is predicted, implying that the absorption rate of the 238U beam by a proton target discerns between the parallel and perpendicular orientations of the deformed 238U nuclei.

质子散射对变形核的取向二色性效应

使用改进的量子分子动力学模型模拟 238U 原子核的质子诱导散射，在束能量高于 100 MeV 时具有球体变形。偏转质子的角度分布对目标原子核对称长轴相对于光束方向的方向高度敏感。结果，在反向运动反应中，预测了取向二色性效应，这意味着质子目标对 238U 光束的吸收率区分变形的 238U 核的平行和垂直方向。
