摘要: 用Bsplines函数基计算了一维多势阱和二维Henon Heiles势的能谱,得到了精度较高的结果.将这一结果与采用高斯基函数计算的结果进行比较,结果表明:Bsplines函数基用于研究一维束缚态问题比高斯函数基方法更方便,具有灵活、可塑性强、效率高等优点,适用于不同形式势作用下的系统的变分求解.

关键词: Bsplines函数, 高斯基函数, 能谱

Abstract: The B splines method is used to calculate eigenvalues for one and two dimensional multi-well potential.Comparisons are made with calculations using Gaussian bases for one dimensional potential.The B splines bases is shown to be accurate,flexible,and efficient.

Key words: B splines bases, Gaussian bases, energy levels
