Abstract (from CDS):

We present a detection of [C I] 3P1-3P0emission in the lensed quasar APM 08279+5255 at z=3.91 using the IRAM Plateau de Bure interferometer. The [C I] line velocity and width are similar to the values of previously detected high-J CO and HCN lines in this source, suggesting that the emission from all of these species arises from the same region. The apparent luminosity of the [C I] line is L'_CI_=(3.1±0.4)x1010 K.km/s.pc2, which implies a neutral carbon mass M_CI_=(4.4±0.6)/mx107 M, where m is the lensing magnification factor. The [C I] line luminosity is consistent with the large molecular gas mass inferred from the nuclear CO line luminosity (∼1011/m.M). We also present an upper limit on the H2O 110-101line luminosity in APM 08279+5255 of L'H2O<1.8x1010 K.km/s.pc2 (3 σ).
