03 January 2022 - Alberto Ribon (hadr-cross-V10-07-22)
- G4ComponentAntiNuclNuclearXS : extension, by Vladimir Uzhinsky, of
the class to compute the cross sections of light anti-nuclei on
hydrogen. This relies on the isospin symmetry assumption, according
to which the properties of the reactions between anti-proton and
light nuclei are equivalent to those between light anti-nuclei and
hydrogen.
21 October 2021 - Alberto Ribon (hadr-cross-V10-07-21)
- G4IonsShenCrossSection : reintroduced this (old) ion-ion cross section
(that was removed in 10.7.ref03), as required by Vladimir Uzhinsky
