Description
MUSASHI can provide 1-1000 eV pbar beams that enable the study of elementary atomic processes of ionisation by antiproton impact and antiprotonic atom (pbarA) formation under single collision conditions. ASACUSA had measured ionisation cross sections of atomic or molecular targets such as D2, He, Ar, etc., down to 2.4 keV. However, atomic collisions at lower energies, especially below 1 keV, remain experimentally unexplored.
The theories of atomic collisions do not agree with each other. Atomic/Molecular collision experiment with MUSASHI beam will provide a unique opportunity to study at further low collision energies and to reveal atomic collision dynamics down to eV region with pbar impact. Possible targets are H, H2, He, Ar, etc., to measure ionisation cross sections and
pbar capture cross sections of H and He.
