摘要：

A photoionization study of CH3I in the presence of dense CO2 (density range: 1.6-10.0 x 10(19) cm-3) revealed the prethreshold 2E3/2 Rydberg transitions of methyl iodide perturbed by CO2. From the measured pressure shift of the nd Rydbergs (n = 11,12,13,14) the scattering length of CO2 was deduced as A = -0.224 nm, in accord with cross-section data. The vibrational structure of CO2 above 9.54 eV was found to be superimposed on the CH3I absorber photoionization spectrum, yielding a spectrum more detailed than absorption spectra of pure CO2.
