Scientific paper

Pressure broadening by molecular hydrogen and helium is one of the major broadening mechanism in the atmosphere of brown dwarfs. He(1 ^1S)-He(2 ^1P) collisional line profiles are determined in a unified theory of spectral line broadening using very recent ab initio potential energies. Results are reported for the conditions prevailing in brown dwarf atmospheres.
