Eigenenergies of a Relativistic Particle in an Infinite Range Linear Potential Using WKB Method
Abstract
Energy eigenvalues for a non-relativistic particle in a linear potential well are available. In this paper we obtain the eigenenergies for a relativistic spin less particle in a similar potential using an extension of the well-known WKB method treating the potential as the time component of a four-vector potential. Since genuine bound states do not exist for positive rising potentials, our calculations are valid only for fairly low-lying levels. The transcendental eigenvalue equation that is obtained is solved using Mathematica software to get eigenenergies. Our results are compared with those for the non-relativistic case. The results may find applications besides having conceptual significance.
