摘要: 通过研究一维量子束缚态的初值解法,导出了一个引理和相关的推论,导出了在经典禁区确定初始条件的计算,进而用“打靶法”简洁直观地确定能量本征值和本征函数.该方法可以推广到求解多维空间径向波动方程.

Abstract: The one-dimensional quantum bound-state solution of the initial value problem is studied. A lemma and an associated inference are derived, as well as a rational formula for choosing initial conditions in the classically forbidden area is obtained. The "shooting method" is used to determine the energy of eigenvalues and eigenfun- tions. The method is simple and intuitive, and can be extended to solve the radial wave function in the multidimen- sional space.
Key words: quantum bound states, initial value solution, shooting method
