Comments: The continuum cross section of oxygen at 296–300 K has been measured with a resolution of 0.13 nm throughout the 
wavelength region 205-241 nm with oxygen pressures from 5 to 760 torr and optical path lengths from 13.3 and 133m.
The values of the Herzberg continuum cross section of oxygen, tabulated at 1 nm intervals in the region 195-241 nm, increase from 
6.3 × 10-24 cm2 at 195 nm to a maximum of 6.6 × 10-24 cm2 at 201 nm and then decrease to 0.85 × 1024 cm2 at 241 nm.
