N2 - 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 2 S1 / 2, 2 P1 / 2 and 2 P3 / 2 is lifted completely, such that new transition channels are allowed.
