Multiple-photon absorption of 16-microm radiation in UF6 at 300 K.
Fluence-dependent optical-absorption parameters were measured in static room-temperature UF(6) at 12 frequencies in the range 615 to 635 cm(-1) and over a fluence range of 0.02 to 8 mJ/cm(2). All data of the average number of photons absorbed per monomer (eta) as a function of fluence (Phi) were fitted to the empirical relation eta = C(1)(v)PhiC(2) (C(2) = 0.8 +/- 0.1). Addition of diluent (N(2)) increased the absorption.
