用基本量子力学解释氢原子
本科生：黄兰指导老师：侯邦品
内容摘要：
主要从以下几个方面来运用基本量子力学解释氢原子。1、氢原子的能级和能量本征函数。首先介绍在量子力学中的波函数，再利用薛定谔方程来导出氢原子的能量本征函数，最后再分析它的物理含义。2、氢原子的四个量子数的物理意义。解释它们其与氢原子的能级的关系。3、径向波函数和角度波函数。主要是得出径向波函数和角度波函数同时给出它的物理意义。4、简并性破除与量子激光。氢原子的内部结构中电子在原子中受到的磁场的作用所产生的正常塞曼效应和反常塞曼效应，以及可能引起的电子跃迁。5、氢原子的Stark效应。氢原子在外场的作用下表现的Stark 效应，这部分将作简单的介绍。
