摘要: 基于 B 样条函数, 通过数值计算方法求解随机势场干扰下氢原子中电子的能量本征问题, 计算了不同幅 值范围的随机势情形下氢原子中电子的本征能量及其本征波函数。结果表明: 氢原子系统受到的随机势强度范 围愈大, 电子分布几率变化越频繁; 量子数越多, 体系越不稳定, 中心力场的作用更容易被外加随机势场破坏。

Abstract: B-spline function is used to solve numerically the energy eigenvalue of electrons in hydrogen atom under the interference of random potential field. The eigen energy and eigen wave function of electrons in hydrogen atom in the case of random potential with different amplitude range are calculated. The results show that the probability of electron distribution changes more frequently when the range of stochastic potential is larger. And the more quantum numbers there are, the more unstable the system becomes, and the more easily the central force field is destroyed by the applied stochastic potential field.

Key words: quantum physics, hydrogen atom, B-spline, random potential field, eigen energy, eigen wave function
