Qualitative analysis of low-lying resonances of the dipositronium emerging from Ps-Ps and Ps-Ps* collisions

Abstract

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.
