We report an experimental study of the low frequency internal friction (LTIF) in solid oxygen in temperature range 7–52 K. Comparison of the temperature dependence of IF with data of x-ray diffraction and other thermodynamic and elastic properties, shows that anomalies of temperature dependence of the internal friction are resulted from phase transitions in solid oxygen.
