摘要
An analysis of channel wave functions is made to clarify the types of resonance emerging from the 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 the existing theoretical results.The existence of a few very probable low-lying narrower resonances,namely the 0^(+)_(1)(A_(2)),1^(-)_(1)(E),…,benefiting from the centrifugal barrier has been suggested.
