$\mathrm{CO}\mathrm{\text{:}}\mathrm{C}(1s)\to {\pi }^{*}$ resonant Auger spectrum detected at 54.7° with respect to the polarization vector in coincidence with ${\mathrm{C}}^{+}$ ions (light gray/red line) and ${\mathrm{CO}}^{+}$ ions (dark gray line). The thin black line represents the sum of both spectra. The plots in the bottom row show the kinetic energy distribution of the ${\mathrm{C}}^{+}$ ions coincident with electrons in the Auger groups that lead to fragmentation.Reuse & Permissions

Figure 2

MFADs of the “$h$” and “$i$” lines for molecules oriented perpendicular to the electric field vector $E$. Upper four panels: Comparison of experimental (top) and theoretical (middle) three-dimensional Auger electron angular distributions. The white sticks indicate the direction of the electric field vector $E$, and its intersection with the C-O axis represents zero intensity. Bottom panels: Auger electron intensity in the plane containing the electric field vector and molecular axis as a function of the angle $\theta$ between electron emission direction and the molecular axis. The gray curve shows the theoretical prediction; the black points the experimental values. All intensities are normalized such that their total 3-D intensity is equal to 1.Reuse & Permissions

Figure 4

Auger electron intensity for emission in the plane containing the molecular axis and the electric field vector plotted as a function of the emission angle in the molecular frame, $\theta$, and the angle between the molecular axis and the electric field, ${\theta }_n^E$ (the molecular axis $z$ is directed from O to C).Reuse & Permissions

Figure 5

Calculated MFAD for the sum of all Auger electrons from the decay of the $\mathrm{CO}\mathrm{\text{:}}\mathrm{C}(1s)\to {\pi }^{*}$ state. The right panel shows two cuts through the MFAD for $\varphi =0$, i.e., in the plane containing the molecular axis and the electric field vector, and $\varphi =90$, i.e., in the plane containing the molecular axis but perpendicular to the electric field vector.Reuse & Permissions
