摘要:

在这项工作中,我们研究的狄拉克方程的矢量和标量势的时空中产生的宇宙弦。利用离心项的近似,得到径向微分方程的解。我们考虑了在Hulthén势下的散射态,得到了相移。从散射$S$ -矩阵的极点的状态的能量确定以及。

英文摘要:

In this work we study the Dirac equation with vector and scalar potentials in the spacetime generated by a cosmic string. Using an approximation for the centrifugal term, a solution for the radial differential equation is obtained. We consider the scattering states under the Hulthén potential and obtain the phase shifts. From the poles of the scattering $S$-matrix the states energies are determined as well.
