C. H. Abstract We present high-resolution CS and (13)CO observations of the central part of the Mon R2 outflow. We find that the accelerated gas is distributed in two opposed, highly fragmented, limb-brightened shells. The fragments in these shells correspond to clumps of gas that, although partaking in the outflow motion, have their own peculiar velocities. The clumps appear in the spectra as secondary components, well separated in velocity from the ambient line. They are as dense as the ambient cloud (few 105/cu cm), and each of them contains several solar mass of gas. From the clumps we directly observe, and from those whose presence we infer by the sudden changes in the shape of the spectra from one position to the other, we conclude that very likely most of -- if not all -- the gas in the Mon R2 outflow is in the form of dense clumps.
