We have detected both ground state fine structure lines of neutral atomic carbon in the IRAS source F10214+4724. The lines are seen at the same redshift (z=2.286) as the optical and CO lines seen previously. The observations were made using the NRAO 12 m and IRAM 30 m telescopes in December 1991. CI is a photodissociation product of CO; its discovery in IRAS F10214 confirms the presence of an intense source of ultraviolet radiation distributed within the source. The [CI] lines appear to be optically thin and to originate in 1E12 to 1E13 M_&sun; of molecular gas. This estimate of the molecular gas mass is comparable to that derived earlier from the CO observations. IRAS F10214 must be forming from an enormous gas reservoir bathed in ultraviolet starlight. A comparison of the CI data from the two telescopes, and mapping done with the 30 m telescope, suggests that the emitting region is structured and the CI is distributed over an angular extent of at least 10''. However, the CI filling factor is small compared to either telescope beam. This is consistent with IRAS F10214 being fragmented and not yet dynamically relaxed: a galaxy in the process of formation. The National Radio Astronomy Observatory is operated by Associated Universities, Inc., under cooperative agreement with the National Science Foundation.
