Altug Arda, Ramazan Sever, Cevdet Tezcan

摘要:

对于任意角动量量子数$\ell$和位置相关质量,近似求解了Hulthén势的Klein-Gordon方程.通过适当的坐标变换,将Klein-Gordon方程转化为Schrödinger型微分方程,得到了相应的解。计算中采用Nikiforov-Uvarov方法,得到了能量本征值和波函数。结果表明,在质量不变的情况下,所得结果与文献中的结果吻合得很好。

英文摘要:

The Klein-Gordon equation is solved approximately for the Hulthén potential for any angular momentum quantum number $\ell$ with the position-dependent mass. Solutions are obtained reducing the Klein-Gordon equation into a Schrödinger-like differential equation by using an appropriate coordinate transformation. The Nikiforov-Uvarov method is used in the calculations to get an energy eigenvalue and and the wave functions. It is found that the results in the case of constant mass are in good agreement with the ones obtained in the literature.
