Scientific paper

In this work we present scanning Fabry-Perot observations of the M51-type interacting galaxy pair KPG 302 (NGC 3893/96), the derivations one can make about the content of visible and dark matter of the components of the pair and a very preliminary analysis of the encounter based on simulations made with an N-body code. The main conclusions we reach are that our kinematics is equally compatible either with NFW dark matter profiles or pseudo-isothermal halo profiles and that the mass-ratio of the galaxies in the pair should be larger than 1/50 in order to develop the observed spiral structure seen in the larger component of the pair.
