Abstract A search for active galactic nuclei among interacting galaxies is reported. A sample of 167 systems of interacting and asymmetric galaxies was observed spectrophotometrically in the spectral range 4700-7100 A. The results are compared with a sample of isolated galaxies. It is found that (1) there are no Seyfert nuclei in elliptical or dwarf irregular galaxies of the sample; (2) there is an excess of Seyfert nuclei among interacting spirals, but it is only at the 90 percent confidence level; (3) this excess becomes statistically significant (98 percent) when only strongly interacting spirals are included (four new Seyfert nuclei are presented); (4) in the subgroup of galaxies with extreme tidal distortions, no Seyfert nuclei were found.
