Note – The energy losses included are those that produce excitation and ionization of atoms as well as those producing recoil atoms.
Note – Les pertes d'énergie comprises dans le pouvoir d'arrêt massique par collisions sont aussi bien celles qui produisent l'excitation et l'ionisation des atomes que celles qui produisent les atomes de recul.
