Dear Colleagues,

Geant4 is a new-generation toolkit for full and fast Monte Carlo particle transport simulations, intended for a wide range of applications; these include high energy physics, space and cosmic ray simulations, nuclear and radiation analysis, and heavy ion and medical applications. A set of physics models has been developed in Geant4 to describe the electromagnetic interactions of photons and electrons with matter down to 250 eV. Preliminary comparisons of the models with experimental data show a good agreement. A CERN preprint report (CERN-OPEN-99-034) on this activity can be downloaded. The Geant4 source code is freely available at http://wwwinfo.cern.ch/asd/geant4/source/source.html.

Further extensions and refinements of these models, as well as low-energy electromagnetic interaction models for protons and ions, are planned by the Geant4 collaboration in future.
