    "abstract": "The quadrupole channel of two-photon double ionization of He exhibits two\ndistinctly different modes of correlated motion of the photoelectron pair. The\nmode associated with the center-of-mass motion favors a large total momentum\nwhich is maximazed at a parallel emission. However, the mode associated with\nthe relative motion favors an antiparallel emission. This difference is\nmanifested in a profoundly different width of the angular correlation functions\ncorresponding to the center-of-mass and relative motion modes.",
