ATOMIC CARBON EMISSION FROM INDIVIDUAL MOLECULAR CLOUDS IN M33

We present observations of the 492 GHz [CI] emission for four individu al giant molecular clouds in the Local Group galaxy M33 obtained with the James Clerk Maxwell Telescope. The average [CI] to CO J = 1-0 inte grated intensity ratio of 0.10 +/- 0.03 is similar to what is observed in Galactic molecular clouds but is smaller than what is seen in star burst galaxies. Similarly, the column density ratio N(C)IN(CO) is simi lar to that observed in the Orion Bar but is smaller than values obtai ned for starburst galaxies. The [CI] line is found to be a more import ant coolant than the lowest three rotational transitions of CO for all the clouds in the sample. The [CI] luminosity does not appear to be e nhanced significantly in two low-metallicity clouds, which may be a re sult of the unusual ionization environment of the clouds.
