    "abstract": "The narrowing of electron and ion wave packets in the process of\nphotoionization is investigated, with the electron-ion recoil fully taken into\naccount. Packet localization of this type is directly related to entanglement\nin the joint quantum state of electron and ion, and to Einstein-Podolsky-Rosen\nlocalization. Experimental observation of such packet-narrowing effects is\nsuggested via coincidence registration by two detectors, with a fixed position\nof one and varying position of the other. A similar effect, typically with an\nenhanced degree of entanglement, is shown to occur in the case of\nphotodissociation of molecules.",
