Abstract : A decrease in inelastic losses is due to the fact that the electrons of the atom have time to accomplish many revolutions before the particle has changed its position appreciably. Owing to this adiabaticity, ionization or atomic excitation attains a low probability. However, there is an additional loss mechanism for negatively charged particles which is effective even in the range of very low velocities and is responsible, apparently, for particle capture by one of the atomic shells. This mechanism is connected with the fact that slow negative particles must be drawn deeply into the atom and accelerated. Let us assume that the negative particle is much heavier than an electron. Then its motion may be described by classical mechanics. (Author)
