In a mercury-nitrogen mixture illuminated with resonant light pulses at wavelength 253.7 nm, metastable Hg(6 3P0) atoms are produced according to the process : Hg(6 3P1) + N2(X1 Σ g+, v = 0) → Hg(6 3P0) + N 2(X 1Σg+, v = 1). It is observed that the decay of the metastable atoms concentration in the post-excitation depends upon the value of the light flux. This feature is partially explained by (i) a nonequilibrium situation for nitrogen molecules in the v = 1 vibrational level (ii) inelastic collisions Hg(6 3P0) + Hg(6 3P0) → Hg(6 1S0) + Hg*, where Hg* is a highly excited mercury atom. Excitation cross-sections for the 8 1S0, 8 3S 1, 6 1D2, 6 3D1, 6 3D2 and 6 3D3 levels have been measured and are respectively 15, 9,12, 4,10 and 6 Å2.Les ...
