Solution of Dirac equation with spin and pseudospin symmetry for an anharmonic oscillator

We present the exact solutions of Dirac equation with anharmonic oscillator potential using the Nikiforov-Uvarov method. Taking into account potentials of vector field V(r) and scalar field S(r) in Dirac Hamiltonian, the bound state energy eigenvalues and the corresponding upper and lower two-component spinors of fermion are obtained. These solutions are considered in the framework of the spin and pseudospin symmetry concept. (C) 2011 American Institute of Physics. [doi:10.1063/1.3532930]
