In the first part of this paper, a separation mechanism accounting for collisions of unmagnetized, ionized clouds of matter and antimatter is proposed which involves an electromagnetic instability that grows at the encounter layer and produces magnetic fields strong enough to separate the clouds after minor interpenetration. The second part of the paper details the way in which the initial interpenetration produces fast electrons and positrons from annihilation which, in turn, produce strong MHD shocks. These MHD shocks impart enough energy to the small ionized component to ionize the neutral fraction and produce a Leidenfrost layer over a period of about ten years, after which interpenetration ceases.
