    "abstract": "The possibility of coherent population trapping in two electron states with\naligned spins (ortho-system) is evidenced. From the analysis of a three-level\natomic system containing two electrons, and driven by the two laser fields\nneeded for coherent population trapping, a conceptually new kind of\ntwo-electron dark state appears. The properties of this trapping are studied\nand are physically interpreted in terms of a dark hole, instead of a dark\ntwo-electron state. This technique, among many other applications, offers the\npossibility of measuring, with subnatural resolution, some superposition-state\nmatrix-elements of the electron-electron correlation that due to their time\ndependent nature are inaccesible by standard measuring procedures.",
