Query: Pekeris-type approximation for the $l$-wave in a P\"oschl-Teller
  potential   An approximation for the centrifugal term which transforms the radial
equation for a particle in a P\"oschl-Teller potential into an exactly solvable
approximate equation is proposed. In contrast to the approximations known in
the literature, the new one can be used with the most general form of the
central P\"oschl-Teller potential. An approximate expression for the
bound-state spectrum is obtained.
