Mechanisms for the suppression of annihilationless breakup of nuclei by low-energy antiprotons
Karmanov V. A., Trukhov A. V.
The mechanism for the suppression (due to the narrowness of the cone in pN scattering) of the cross section for annihilationless breakup of nuclei by antiprotons is rapidly replaced by a different mechanism (which is linked with the large pN annihilation cross section) on going from a deuteron to heavier nuclei. Both mechanisms are equally important in the ρ 4He interaction studied experimentally by Batusov etal. (Brief Communications JINR No. 12-85, Dubna, 1985, p. 6) and Balestra<?/я/. [Phys. Lett 194B, 343 (1987) ].
