量子力学中一种新的近似方案

A new approximation scheme in quantum mechanics

Sang Koo You, Kwang Joe Jeon, Chul Koo Kim, Kyun Nahm

摘要:

将微扰理论与变分计算相结合,构造了一种求解量子力学问题的近似方法。以非简谐振子和He原子为例,说明本文方法提供了一个有效的估计基态和激发态的方案。我们还讨论了本方法的局限性。

英文摘要:

An approximation method which combines the perturbation theory with the variational calculation is constructed for quantum mechanical problems. Using the anharmonic oscillator and the He atom as examples, we show that the present method provides an efficient scheme in estimating both the ground and the excited states. We also discuss the limitations of the present method.
