Abstract

We study the 2e2e+ equal-mass charge-neutral four-body system in the adiabatic hyperspherical framework. The lowest few adiabatic potentials are calculated for zero orbital angular momentum, positive parity, and charge conjugation symmetries. Propagating the R matrix, the low-energy s-wave scattering lengths of the singlet-singlet and triplet-triplet spin configurations are calculated. Last, we calculate the S matrix for energies above the ionic threshold to estimate the transition rates between the single ionic fragmentation channel and the lowest few dimer-dimer fragmentation channels.
