弹性散射和非弹性散射弹性散射和非弹性散射elasticscatteringandinelasticscattering使用粒子间碰撞来研究粒子的性质、相互作用和内部结构的两种情况。如果碰撞过程中两粒子间只有动能的交换，粒子类型、其内部运动状态和数目并无变化，则称为弹性散射或弹性碰撞。如果碰撞过程中除了有动能交换外，粒子的数目、类型和内部状态有所改变或转化为其他粒子，则称为非弹性散射或非弹性碰撞。散射过程的研究对于了解许多物理现象具有很重要的意义。例如E.卢瑟福对a粒子被物质散射的研究，提出原子的有核模型；J.弗兰克和G.L.赫兹的电子与原子碰撞实验证实了N.玻尔的定态假设；建造高能加速器就是利用被加速粒子的散射过程来研究粒子的性质、相互作用和相互转化的规律。60年代末到70年代初利用高能轻子对质子和中子的深度非弹性散射的实验，发现质子和中子内部存在点状结构。
