论文摘要
卢瑟福散射通常是通过将弹丸在经典或量子机械平面波上处理而描述的。在这里，我们将它们视为波数据包，并研究其与固定靶核的正面碰撞。我们模拟了该一维系统的量子动力学，并研究了平均量子解与经典溶液的偏差。这些偏差可追溯到库仑电势的凸特性。最后，我们概述了如何在寻找核反应开始的实验中测试这些理论发现。
Rutherford scattering is usually described by treating the projectile either classically or as quantum mechanical plane waves. Here we treat them as wave packets and study their head-on collisions with the stationary target nuclei. We simulate the quantum dynamics of this one-dimensional system and study deviations of the average quantum solution from the classical one. These deviations are traced back to the convexity properties of Coulomb potential. Finally, we sketch how these theoretical findings could be tested in experiments looking for the onset of nuclear reactions.
