Photoelectron circular dichroism in the multiphoton ionization by short laser pulses: II. Three- and four-photon ionization of fenchone and camphor

Abstract

Angle-resolved multiphoton ionization of fenchone and camphor by short intense laser pulses is computed by the time-dependent Single Center (TDSC) method. Thereby, the photoelectron circular dichroism (PECD) in the three-photon resonance enhanced ionization and four-photon above-threshold ionization of these molecules is investigated in detail. The computational results are in a satisfactory agreement with the available experimental data, measured for randomly-oriented fenchone and camphor molecules at different wavelengths of the exciting pulses. We predict a significant enhancement of the multiphoton PECD for uniaxially-oriented fenchone and camphor.
