| Abstract: | A new ring-shaped non-harmonic oscillator potential is proposed. The exact bound solution of Dirac equation for the above potential is obtained under the condition of equal scalar and vector potentials. Dirac equation can be separated into an angular equation and a radial equation with the help of separation variable. The normalized angle wave function expressed and radial wave function expressed respectively in terms of the universal associated-Legendre function and the confluent hypergeometric function are presented. The exact energy spectrum equations are obtained and meanwhile, proper discussion and some important conclusions are presented. |
