Description
The antinucleon-nuclei annihilation cross sections at low energies were systematicaly measured at CERN in the 80's and 90's with the LEAR facility and later with the Antiproton Decelerator. Unfortunately only few data exist for very low energy antiprotons (p<500 MeV/c) on medium and heavy nuclei.
A deeper knowledge is required by fundamental physics and can have consequence also in cosmology and medical physics.
In order to fill the gap, the ASACUSA Collaboration has very recently measured the annihilation cross section of 100 MeV/c antiproton on carbon.
In the present work the experimental result is presented together with a comparison both with the antineutron data on the same target at the same energies and with the other existing antiproton data at higher energies.
