- Abstract summary: The paper deals with the Compton disintegration of positronium and a comparison of the differential cross sections of this process with the similar cross sections in the case of the Compton ionization of the hydrogen atom.
Special attention is paid to the resonances arising, when the electron and positron move parallel to each other in continuum states with the same velocities and zero relative momentum.

- Abstract: The paper deals with the Compton disintegration of positronium and a
comparison of the differential cross sections of this process with the similar
cross sections in the case of the Compton ionization of the hydrogen atom.
Special attention is paid to the resonances arising, when the electron and
positron move parallel to each other in continuum states with the same
velocities and zero relative momentum. It is likely that a manifestation of
this effect in the double differential cross section is found as an additional
peak, which grows with a decrease in the photon energy.

Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.
