Abstract: | We have derived a simple analytical expression which completely characterizes entanglement properties of the spin state of a photo-Auger electron pair. These two electrons are sequentially emitted from a rotating linear molecule in the absence of any spin-dependent interactions. This expression comes out to be identical to that already obtained [Chandra and Ghosh, Phys. Rev. A 70 (2004) 060306(R)] for similar studies in atomic targets without spin–orbit interaction. Thus, inner-shell ionization of both atoms and of linear molecules becomes a readily available universal factory for producing bipartite entangled states of electrons. |
