The photoabsorption cross section of the Ar2F excimer in the lowest excited state (42Γ), which is produced by exciting an Ar/F2 gas mix by a short-pulse relativistic electron beam, has been determined at 248 nm to be (3.3 ± 1) × 10−18 cm2 by observing the depletion of Ar2F fluorescence induced by the irradiation of a short-pulse KrF laser beam. Observation of ArF fluorescence shows that the Ar2F excimer is directly dissociated into ArF and Ar by absorbing a 248-nm photon.
