Dirac Equation in Noncommutative Space for Hydrogen Atom
Abstract
We consider the energy levels of a hydrogen-like atom in the framework of θ -modified, due to space noncommutativity, Dirac equation with Coulomb field. It is shown that on the noncommutative (NC) space the degeneracy of the levels 2S1/2, 2P1/2 and 2P3/2 is lifted completely, such that new transition channels are allowed.
