We present the solutions of the Schro¨dinger equation with the
Hultheˊn potential plus ring-shape potential for ℓ=0 states
within the framework of an exponential approximation of the centrifugal
potential.Solutions to the corresponding angular and radial equations are
obtained in terms of special functions using the conventional Nikiforov-Uvarov
method. The normalization constant for the Hultheˊn potential is also
computed.Comment: Typed with LateX,12 Pages, Typos correcte
