    "abstract": "The collisionless expansion of spherical plasmas composed of cold ions and\nhot electrons is analyzed using a novel kinetic model, with special emphasis on\nthe influence of the electron dynamics. Simple, general laws are found,\nrelating the relevant expansion features to the initial conditions of the\nplasma, determined from a single dimensionless parameter. A transition is\nidentified in the behavior of the ion energy spectrum, which is monotonic only\nfor high electron temperatures, otherwise exhibiting a local peak far from the\ncutoff energy.",
