We present evidence for a young stellar population component in the early-type member of the E+S galaxy pair AM 0327-285. This young population is consistent with the occurrence of cross-fueling in this interacting system. We used spectroscopy, optical imaging, IRAS data, and stellar population synthesis to study the stellar content in the early-type galaxy. We also attempted to date episodes of star formation in its nu clear region, from population synthesis and basic dynamical considerations. The dominant population is old and metal-rich ((Z/Z)0=0.3) while rv 10% of the flux at 5870 A arises from a superimposed young stellar population with age :S 5 x 108 yr. This age is close to several estimates of the characteristic timescale of the interaction, suggesting that the mass influx as sociated with this star formation occurred as a result of an earlier phase of the interaction and not as a result of the present geom etry of the pair.
