Electron dynamics in the carbon atom induced by spin-orbit interaction

الأصل · EN

We use R-Matrix theory with Time dependence (RMT) to investigate multiphoton ionization of ground-state atomic carbon with initial orbital magnetic quantum number Mₗ=0 and Mₗ=1 at a laser wavelength of 390 nm and peak intensity of 10¹⁴ W cm⁻². Significant differences in ionization yield and ejected-electron momentum distribution are observed between the two values for Mₗ. We use our theoretical results to model how the spin-orbit interaction affects electron emission along the laser polarization axis. Under the assumption that an initial C atom is prepared at zero time delay with Mₗ=0, the dynamics with respect to time delay of an ionizing probe pulse modelled using RMT theory is found to be in good agreement with available experimental data.
