    "abstract": "The electron and positron acceleration in the first cycle of a laser-driven\nwakefield is investigated. Separatrices between different types of the particle\nmotion (confined, reflected by the wakefield or ponderomotive potential and\ntransient) are demonstrated. The ponderomotive acceleration is negligible for\nelectrons but is substantial for positrons. An electron bunch, injected as\nquasi-monoenergetic, acquires a localized energy spectrum with a cut-off at the\nmaximum energy.",
