The stopping of partially stripped ions by a partially ionized target is investigated for the case of a projectile with an extended electronic core. Long-ranged contributions to energy loss are evaluated within an impact-parameter theoretical framework. Quantities correcting the standard pointlike results are given in analytical form with the aid of a Thomas-Fermi-like effective interaction. They can be substantial for moderate projectile ionicity and for velocities relevant for inertial confinement fusion driven by intense ion beams. As a rule, the stopping quantities pertaining to projectiles with extended core taken into account lie above those computed for their pointlike homologs.
