  We investigate in details the kinematics and morphology of the Seyfert galaxy
NGC6104 in order to identify the mechanism of gas transportation to the active
galactic nucleus (AGN). Our observational data were obtained at the 6-m Special
Astrophysical Observatory telescope with the MPFS integral-field spectrograph
and the SCORPIO universal device in three modes: direct imaging, a scanning
Fabry-Perot interferometer, and long-slit spectroscopy. Images from the HST
archive were invoked to study the structure of the circumnuclear region. An
analysis of deep images has revealed that NGC6104 is in the phase of active
merging with a companion galaxy. We have been able to study the detailed
picture of ionized gas motions up to galactocentric distances of 14 kpc and to
construct the stellar velocity field for the inner region. The radial gas
motions toward the AGN along the central bar play a significant role at
galactocentric distances of 1-5 kpc. In addition, we have detected an outflow
of ionized gas from the nucleus that presumably resulted from the intrusion of
a radio jet into the ambient interstellar medium. Using diagnostic diagrams, we
estimate the contributions from the AGN and star formation to the galactic gas
ionization. We estimate the bar pattern speed by the Tremaine-Weinberg method
and show that the inner ring observed in the galactic images has a resonant
nature. Two possible ring formation scenarios (before and during the
interaction with a companion) are discussed.
