1.1解：根据卢瑟福散射公式：

200222442K Mv ctg b b Ze Ze

αθπεπε== 得到：

Ze ctg ctg b K ο

θαπεπ---??===??????米 式中212K Mv α=是α粒子的功能。 1.2已知散射角为θ的α粒子与散射核的最短距离为

2202121()(1)4sin m Ze r Mv θπε=+ ，

试问上题α粒子与散射的金原子核之间的最短距离m r 多

大？

解：将1.1题中各量代入m r 的表达式，得：

与金箔。问质子与金箔原子核可能达到的最小距离多大？又问如果用同样能量的氘核（氘核带一个e +电荷而质量是质子的两倍，是氢的一种同位素的原子核）代替质子，其与金箔原子核的最小距离多大？

解：当入射粒子与靶核对心碰撞时，散射角为180ο。当
