N2 - A finite-range interaction model is introduced into the calculation of strong-interaction level-shifts and -widths in pionic atoms by modifying the Ericson-Ericson local optical potential. The resulting integro-differential equation is solved numerically in coordinate space for 1s and 2p levels in light N=Z nuclei. We show that genuine finite-range effects within the present model can be opposite to those found when nuclear densities are inflated to mock up a finite-range interaction.
