H2 MOLECULE LINES IN RHO-OPH CLOUD UV RADIATION FIELD IN DARK CLOUDS

we propose to observe several h2 molecular lines with iso/sws in the rhooph dark cloud. in this proposal, more time is being requested for tonaka.wdism_1 and tonaka.wdism_2. we have observed the nearby star forming region, rho oph cloud, in farinfrared wavelength with a balloonborne telescope, and in mid and farinfrared wavelength with lws and sws. up to now, many observations of active star forming regions have been made in many wavelength. however, the physical conditions in relatively quiet starforming regions are still unknown. rho oph cloud is one of the most general interstellar cloud with moderate uv field, gas temperature, and density. at the first call observation of the rho oph cloud with sws, we have detected spectrum of a high excitation energy level of h2 molecule (00 s(3)), which unexpectedly suggests ubiquitous uv radiation in the dark cloud. more information is strongly needed to understand the molecular processes in warm interstellar cloud surrounded moderate uv field. therefore, observations of several h2 excitation lines are very important for this study. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
