摘要
首先给出了核反应过程中入射粒子阈能公式的一种推导方法,然后,通过考察推导过程和公式的结构,证明了在入射粒子动能等于阈能的情况下,核反应一定是同一条直线上的完全非弹性碰撞.
An approach for calculating the threshold energy for incident particles is introduced. By discussing the structure of calculation formula, we prove that the nuclear reaction must be completely inelastic collision on same straight line when the kinetic energy of incident particle is equal to threshold energy.
