库仑势加新环形势的相对论束缚态

The exact solutions of bound states of Klein-Gordon equation and Dirac equation with Coulomb potential plus a new ring-shaped potentials are studied on the assumption that the scalar potential is equal to the vector potential. The exact energy expressions and the normalized wave functions for Klein-Gordon equation are presented. The exact energy expressions and the normalized spinor wave functions for Dirac equation are given.
