On the different role of protons and neutrons in antinucleon annihilations on nuclei
A. Bianconi, G. Bonomi, M. P. Bussa +4
We compare data of antineutron and antiproton annihilation cross sections on different targets at very low energies. After subtracting Coulomb effects, we observe that the ratio be…
Limits on the low energy antinucleon-nucleus annihilations from the Heisenberg principle
A. Bianconi, G. Bonomi, M. P. Bussa +3
We show that the quantum uncertainty principle puts some limits on the effectiveness of the antinucleon-nucleus annihilation at very low energies. This is caused by the fact that t…
A phenomenological analysis of antiproton interactions at low energies
A. Bianconi, G. Bonomi, M. P. Bussa +3
We present an optical potential analysis of the antiproton-proton interactions at low energies. Our optical potential is purely phenomenological, and has been parametrized on data…
Coulomb corrections to low energy antiproton annihilation cross sections on protons and nuclei
A. Bianconi, G. Bonomi, E. Lodi Rizzini +2
We calculate, in a systematic way, the enhancement effect on antiproton-proton and antiproton-nucleus annihilation cross sections at low energy due to the initial state electrostat…
Antiproton annihilation on light nuclei at very low energies
K. V. Protasov, G. Bonomi, E. Lodi Rizzini +1
The recent experimental data obtained by the OBELIX group on D and He total annihilation cross sections are analyzed. The combined analysis of these data with e…
Annihilation of antiprotons on nuclear targets at low energies: a simple analysis
A. Bianconi, G. Bonomi, E. Lodi Rizzini +2
We set up a plane wave impulse approximation (PWIA) formalism for the analysis of the annihilation cross sections of antinucleons on nuclear targets at very low momenta (below 100…
