Low energy models (250 eV to 100 GeV) for electrons and photons, based on the LLNL database Low energy models for positive charged hadrons Unique to Geant4
Based on experimental data (where available) + theoretical model Low energy models for positive charged ions Ziegler and ICRU databases and parametrisations Low energy models for negative charged hadrons Extensions to lower energies foreseen Alternative models foreseen
Models for positrons foreseen Negative ions foreseen Polarised models Compton already implemented, other in progress Maria Grazia Pia, INFN Genova Low energy e.m. extensions Fundamental for space and medical applications, neutrino experiments, antimatter spectroscopy etc. e, down to 250 eV
