| 摘 要： | 对卢瑟福散射公式在小角度上的有效性进行了研究．当靶箔近似为平面时，用简单的几何关系得到了散射角下限的计算公式．用半经典方法讨论了屏蔽效应的影响．确定了卢瑟福散射公式的有效性取决于α粒子在靶箔内只经过一次散射假定的有效性．

| Abstract: | The effectiveness of Rutherford's scattering formula depends on the assumed effectiveness of the once scattering if α-particle in the target foil. A simple geometric method can be used to determine its angle-limit when the target foil is approximately considered as a plane. |
