Query: Qualitative analysis of low-lying resonances of the dipositronium
  emerging from Ps-Ps and Ps-Ps* collisions   An analysis of the channel wave functions is made to clarify the types of
resonance emerging from Ps-Ps and Ps-Ps* collisions. The ordering of the energy
levels of the states of the dipositronium is evaluated based on the inherent
nodal structures of wave functions and on existing theoretical results. A few
very probable low-lying narrower resonances, namely the 0+(A2), 1-(E),...,
benefiting from the centrifugal barrier have been proposed.
