The CI lines as tracers of molecular gas, and their prospects at high redshifts

open access: yes, 2004
We examine the fine structure lines $^{3}P_{1}\to $$^{3}P_{0}$ (492 GHz) and $ ^{3}P_2\to $$^{3}P_1$ (809 GHz) of neutral atomic carbon as bulk molecular gas mass tracers and find that they can be good and on many occasions better than $ ^{12}$CO ...
