|Title:||Cross Sections And Asymmetry Parameters For Photoionization Of Ch3 F In The Vuv Region|
|Author:||dos Santos A.S.|
|Abstract:||Calculated cross sections and asymmetry parameters for photoionization of the three outermost valence orbitals of CH3 F for photon energies from near threshold to 50 eV are reported. The photoelectron continuum orbitals are obtained using the Schwinger variational method at the level of static-exchange plus correlation potential. Our results are compared with other theoretical and experimental results showing a good quantitative agreement. Correlation effects do not significantly affect the computed total cross sections and photoelectron asymmetry parameters. The broader structure that appears in the experimental cross section are well described. However, the narrow resonant features near threshold are not found in the present one-electron treatment of the photoionization process. © 2009 Elsevier B.V. All rights reserved.|
