In a departure from our previous work modeling antiproton capture on helium, with its relatively straightforward, fixed center target, extending the semiclassical approach to molecular hydrogen, a multicenter target with target masses identical to the projectile, requires that we reconsider the fundamental nature of our model, in particular the momentum-dependent Heisenberg core used to stabilize electrons in the ground state. Here we discuss the main features of our Kirschbaum-Wilets model of molecular hydrogen as it is calibrated against proton collision data, and then used to study antiproton collisions. Details of the collision process are presented, including the energy and angular momentum states of incident antiprotons that result in formation of pp, and the resulting distribution of protonium atomic states.
