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

An analysis of channel wave functions is made to clarify the types of reson ance emerging from the Ps-Ps and Ps-Ps* collisions. The ordering of the ene rgy levels of the states of the dipositronium is evaluated based on the inh erent nodal structures of wave functions and on the existing theoretical re sults. The existence of a few very probable low-lying narrower resonances, namely the 0(1)(+)(A(2)), 1(1)(-)(E),..., benefiting from the centrifugal b arrier has been suggested.
