Abstract

The Schrödinger equation is solved numerically for charmonium using the discrete variable representation (DVR) method. The Hamiltonian matrix is constructed and diagonalized to obtain the eigenvalues and eigenfunctions. Using these eigenvalues and eigenfunctions, spectra and various decay widths are calculated. The obtained results are in good agreement with other numerical methods and with experiments.

离散变量表示(DVR)方法的Charmonium性质

采用离散变量表示（DVR）方法对碳的薛定谔方程进行了数值求解。构造并对角化哈密顿矩阵，得到特征值和本征函数。利用这些本征值和本征函数，计算了光谱和各种衰变宽度。所得结果与其他数值方法及实验结果吻合较好。
