摘要: 从有心力遵循的两个基本守恒律出发,证明α粒子散射的轨道方程为远枝双曲线;根据几何关系证明了瞄准距离等于轨道半虚轴,从而简便地导出瞄准距离与散射角的关系式.

关键词: α粒子散射, 守恒定律, 瞄准距离, 远枝双曲线

Abstract: Starting from two basic conservation laws for the central force, the far-branch hyperbola of scattering orbit of the α-particle is deduced. According to the geometric relationship, the sighting range being equal to the orbital semi-imaginary axis is proved, thus the relationship between the sighting range and scattering angle is easily derived.

Key words: α-particle scattering, conservation law, sighting range, far-branch hyperbola
