In this work,a study of O2:He inelastic collisions from 10 to 40K will be presented.For that purpose,a number of supersonic microjets of O2:He mixtures free from O2 condensation,with O2 mole fractions ranging from 0.025 to 0.50,have been quantitatively characterized in terms of number densities n(z) and rotational populations PJ(z) along the jet direction(z) by means of the rotational and vibrational Raman spectra.
