Circular dichroism in K-shell ionization from fixed-in-space CO and N_ 2

We present results of calculations of the angular distributions of K-shell photoelectrons from fixed-in-space CO and N_2 molecules emitted by circularly polarized light. These calculated distributions account well for the strong circular dichroism recently reported in measurements of photoelectron distributions in these two systems. The calculations also serve to identify regions of photoelectron energy where pronounced circular dichroism can be expected in these spectra.
