An exploratory study of antiproton-nucleus scattering

Abstract

An exploratory study of/7-nucleus scattering at low and medium energies (< 200 MeV) is presented using optical potentials which are representative of those either derived from/7-atomic data or calculated theoretically. The elastic differential cross sections are sensitive to the potential characteristics. Some indicative cases of inelastic scattering were also examined. Reaction cross sections are discussed and compared to recent measurements.

Semi-classical approach to antiproton-nucleus scattering

“…During the last two decades, information generated by heavy-ion scattering (HIS) has evolved as a major area of nuclear physics. More recently, scattering and reaction experiments conducted on different nuclei using the antiproton (if) as projectile have initiated a new line of exploration of the nuclei (Garreta et al 1984;Kronenfeld et al 1984;Mackellar et al 1984;Kubo et al 1985;Ingemarsson 1986;Janouin et a11986) which is of much interest due to several reasons. These can provide a better idea of the interaction of antiprotons with nuclear matter, antiproton-nucleus potentials, additional reaction channels due to annihilation of antiproton etc.…”
