Abstract

Maps are presented of P-3(1)-->P-3(0) [C I] and J=2-->1 (CO)-O-18 line emission from the interstellar molecular cloud G35.2-0.74N. The maps are interpreted with reference to a previous model for the structure of the cloud in which opposing jets from a central object, embedded in a rotating interstellar disc, precess and drive a bipolar molecular outflow. The (CO)-O-18 emission traces the rotating interstellar disc, but the [C I]] emission shows several features. An unresolved component is observed which probably results from dissociation of CO in the centre of the disc by UV radiation from the central source. Background [C I] emission is also observed which shares the rotation of the disc on larger scales. The C I/CO ratio in these components is typically a few per cent. High-velocity [C I] emission, where C I/CO is high (> 0.1-0.4), is observed between the CO molecular outflow and the cavity exacavated by the jet. This material has probably been accelerated by the jet but dissociated by far-UV radiation propagating through the cavity. The C I/CO ratio falls as the shocked outflow later sweeps up CO.
