Perturbed Coulomb potentials in the Klein - Gordon equation via the shifted - l expansion technique


A shifted l expansion technique is introduced to calculate the energy eigenvalues for Klein Gordon (KG) equation with Lorentz vector and/or Lorentz scalar potentials. Although it applies to any spherically symmetric potential, those that include Coulomb like terms are only considered. Exact eigenvalues for a Lorentz vector or a Lorentz scalar, and an… (More)
