We study the kinematics and dynamics of the M51-type interacting galaxy pairKPG 302 (NGC 3893/96). We analyse the distribution of the dark matter (DM) haloof the main galaxy in order to explore possible differences between DM halos of"isolated" galaxies and those of galaxies belonging to a pair. The velocityfield of each galaxy was obtained using scanning Fabry-Perot interferometry. Atwo-dimensional kinematic and dynamical analysis of each galaxy and the pair asa whole is done emphasizing the contribution of circular and non-circularvelocities. Non-circular motions can be traced on the rotation curves of eachgalaxy allowing us to differentiate between motions associated to particularfeatures and motions that reflect the global mass distribution of the galaxy.For the main galaxy of the pair, NGC 3893, optical kinematic information iscomplemented with HI observations from the literature to build amulti-wavelength rotation curve. We try to fit this curve with amass-distribution model using different DM halos. We find that themulti-wavelength rotation curve of NGC 3893, "cleaned" from the effect ofnon-circular motions, cannot be fitted neither by a pseudo-isothermal nor by aNFW DM halo.Comment: Accepted for publication in A&A. 11 pages, 9 figures and 2 table
