Image of the week: double-photo ionization

This week’s Image of the Week is taken from a recent JPhysB paper in which theoretical methods are used to study the photo-double ionization of carbon dioxide.  O Alwan et al determine the multiply differential cross section of a CO2 molecule which has been doubly ionized by a polarized photon.  The molecule ejects two electrons at different angles, and the cross section varies with the angle of ejection, which is what this image shows.
