The "halo" variety of these objects is found near drip lines. An equation modeling these objects includes pairing, asymmetry, and surface terms and is based on Gamow's liquid drop model. That equation fails to predict the increase in stability in these objects at certain "magic numbers" such as 2 and 8. Their existence was discovered in an experiment in which alpha particles were deflected by a sheet of gold, and J. J. Thomson's plum pudding model of the atom lacked this structure. For 10 points, name this center of an atom which contains protons and neutrons.
