Résumé :

A simple analytical relation giving the range of a heavy charged particle (p, α, ...) as a function of its initial kinetic energy is established. This relation contains two parameters, depending on the medium. The ranges calculated are in agreement with the experimental results; the precision is of 1% at the non relativistic energies, which is comparable with the precision given by Vigneron's method. An approximate relation, more rapidly calculable, gives a precision of 2 or 3%. Curves are established in three media: photographic emulsion, air and aluminium. © 1955 Società Italiana di Fisica.
