微扰库仑模型中束缚态和共振态的计算

Calculation of bound states and resonances in perturbed Coulomb models

Francisco M. Fernandez

摘要:

本文用Riccati-Padé方法计算了两个有趣的微扰库仑模型的束缚态和共振态。这种方法是基于一个修改后的对数导数的本征函数的有理逼近,并产生序列的汉克尔行列式的根收敛到方程的本征值。

英文摘要:

We calculate accurate bound states and resonances of two interesting perturbed Coulomb models by means of the Riccati-Padé method. This approach is based on a rational approximation to a modified logarithmic derivative of the eigenfunction and produces sequences of roots of Hankel determinants that converge towards the eigenvalues of the equation.
