摘要:

利用参数Nikiforov-Uvarov方法,在离心势近似的框架下,给出了具有Yukawa势的Klein-Gordon方程的解析解.得到了能量本征值和相应的波函数。详细研究了标量势和矢量势的能量以及屏蔽参数对标量势和矢量势能量的影响。得到了非相对论极限,并进行了数值计算。结果表明,我们的计算结果与文献中的结果在质量不变和非相对论极限下是一致的。

英文摘要:

The analytical solutions of the Klein-Gordon equation with the Yukawa potential is presented within the framework of an approximation to the centrifugal potential for any arbitrary state with the position-dependent mass using the parametric Nikiforov-Uvarov method. The energy eigenvalues and the corresponding wave function have been obtained. The energy for both the scalar potential and vector potential as well as the effect of the screening parameter on each of the energy for scalar potential and vector potential are investigated in detail. The nonrelativistic limit is obtained and numerical results are computed. It is found that our results for the constant mass and that of the nonrelativistic limit are in good agreement with the one in the literature.
