Abstract :
We present photoionization spectra of C2H5I and C6H6 doped into Ar and SF6, and photoabsorption spectra of C2H5I doped into Ar. The observation of subthreshold photoionization in C2H5I/SF6 and C6H6/SF6 is discussed in terms of dopant (D)/perturber (P) interactions involving the excited state processes of D*+P→D++P− and D*+P→[DP]++e−, where D* is a discrete Rydberg state of the dopant. The density-dependent energy shifts of high-n Rydberg states observed in the subthreshold photoionization spectra are used to obtain the zero-kinetic-energy electron scattering length for SF6. Similarly, the zero-kinetic-energy electron scattering length of Ar obtained from the density-dependent energy shifts of C2H5I Rydberg states is presented. (Electron scattering lengths obtained here for SF6 and Ar accord with values previously obtained using the density-dependent energy shifts of high-n Rydberg states of CH3I doped into these two perturber gases.)
