Die Schallabsorption in CO₂Ar-Mischungen

Measurements of the sound absorption in C0₂-Ar mixtures up to 90% argon (at frequencies between 1 and 5 kc/s and pressures between 20 and 700 Torr) show an 8-fold increase in the C0₂ relaxation time. The relaxation velocity does not change in linear fashion with the argon concentration.
