Aims: This investigation was undertaken to determine the absorption cross sections of oxygen in the VUV region at temperatures <50 K. Methods: The absorption spectra of gaseous samples cooled with a slit jet and near 300 K were measured with the same absorption system coupled to the VUV beam line of a synchrotron. Results: The maximum absorption cross section for the transition from X 3Σg- v = 0 to state E 3Σu- v = 0 for 16O2 at 38 K was determined to be 98.7 Mb (or 9.87×10-18 cm2). The value of this maximum absorption cross section at 38 K is 1.7 times the value at 303.7 K.
