Query: Study of a confined Hydrogen-like atom by the Asymptotic Iteration
  Method   The asymptotic iteration method (AIM) is used to obtain both special exact
solutions and general approximate solutions for a Hydrogen-like atom confined
in a spherical box of arbitrary radius R. Critical box radii, at which states
are no longer bound, are also calculated. The results are compared with those
in the literature.
