    "abstract": "We illustrate how attosecond light pulses can be used to directly mapping out\nthe time-dependence of the correlated motion of two excited atomic electrons,\ndiscuss how the two-electron correlations manifest themselves in realistic\nattosecond measurements, and propose the following for experimental\nexploration:\n  (a) The single ionization signals which directly reveal bending-vibrational\nmotion of the correlated electron pair,\n  (b) and also its rotational motion.\n  (c) The double ionization signals which directly reveal the two-electron\ndensity in momentum space. To facilitate the description of the above points,\nuse is made of simple wave packets of doubly-excited states of helium.",
