Measurement of the ozone absorption cross-section at the 253.7 nm mercury lineThe absorption cross-section of ozone at 253.7 nm is frequently used as a standard for the entire UV wavelength range. The presently accepted value is 1.147 x 10 to the -17th/sq cm, which is known with an uncertainty of about 2 percent. The cross-section has been recently measured by simultaneously monitoring the ozone pressure, the impurities in the ozone gas, the gas temperature, and the UV beam intensity. The cross-section at room temperature was found to be 1.137 x 10 to the -17th/sq cm having an uncertainty of + or - .7 percent. The improved accuracy will aid a number of ozone experiments including the in situ photometers and Solar Backscatter Ultraviolet instruments.
