WebThe derivation of the Bethe-Bloch equation assumes that the projectile velocity is much larger than the characteristic orbital electron velocities. When the projectile velocity is lower than the requirements of this condition, dE/dx must go to zero as the particle energy approaches zero. A WebThe Bethe formula is only valid for energies high enough so that the charged atomic particle (the ion) does not carry any atomic electrons with it. At smaller energies, …

WebBy use of classical mechanics, Bohr developed an equation of stopping power, -dE/dx, given as the product of a kinematic factor and a stopping number. The kinematic factor includes such terms as the electronic charge and mass, the number of atoms per cubic centimetre of the medium, and the velocity of the incident charged particle. The stopping … Bethe found his formula using quantum mechanical perturbation theory. Hence, his result is proportional to the square of the charge z of the particle. The description can be improved by considering corrections which correspond to higher powers of z.
