In order to analyze the photometric signature of gravitational interactions in spiral and elliptical galaxies, we present results of multicolor broad band (BVRI) surface photometry for a set of 42 mixed pairs drawn from the Karachentsev Catalogue of Isolated Pairs of Galaxies (KPG, [3]). It is generally believed that a high percentage of AGN have close neighbors implying an AGN-interaction connection. The presence of these galaxies in mixed pairs (13 of 84 in our sample) supports the notion that the triggering mechanism for their nuclear activity is of tidal origin and that it does not depend strongly on the type of perturbing galaxy.
