It has long been known that activity in galaxies can be triggered by gravitational interaction. This hypothesis is supported by direct observations which show that a considerable excess of Seyfert galaxies and low redshift QSO's belongs to an interacting or disturbed system. A typical member of this class of objects is the S1 galaxy NGC6240, which is characterized by two close nuclei and is also an outstanding member of the new class of extreme IR galaxies identified by IRAS. High resolution imaging of the region between the two nuclei, using the FOC F/96 camera in combination with narrow band filters, centered on crucial lines and on the continuum, will provide information on the nature and on the effects of the collision between the two nuclei.
