Field ionization and photoionization of CH sub(3)I perturbed by diatomic molecules: electron scattering in H sub(2), HD, D sub(2) and O sub(2)

Field ionization and photoionization of CH sub(3)I perturbed by diatomic molecules: electron scattering in H sub(2), HD, D sub(2) and O sub(2)

Photoionization and field ionization studies of CH sub(3)I doped into the diatomics H sub(2), HD, D sub(2) and O sub(2) (up to a density of 1.0 x 10 super(21) cm super(-3)) are presented. These data are used to extract the zero-kinetic-energy electron scattering length of each diatomic molecule from...

Zusammenfassung:Photoionization and field ionization studies of CH sub(3)I doped into the diatomics H sub(2), HD, D sub(2) and O sub(2) (up to a density of 1.0 x 10 super(21) cm super(-3)) are presented. These data are used to extract the zero-kinetic-energy electron scattering length of each diatomic molecule from the density-dependent shift of the CH sub(3)I ionization energy. Scattering lengths obtained from fits of the photoionization spectra are compared to those determined from field ionization measurements.
