摘要

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 pro-tons 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.
