    "abstract": "A semi-classical, many-body atomic model incorporating a momentum-dependent\nHeisenberg core to stabilize atomic electrons is used to study antiproton\ncapture on Helium. Details of the antiproton collisions leading to eventual\ncapture are presented, including the energy and angular momentum states of\nincident antiprotons which result in capture via single or double electron\nionization, i.e. into [He$^{++}\\,\\bar p$ or He$^{+}\\,\\bar p$], and the\ndistribution of energy and angular momentum states following the Auger cascade.\nThese final states are discussed in light of recently reported, anomalously\nlong-lived antiproton states observed in liquid He.",
