Dechanneling of particles by gas bubbles
Description
The dechanneling probability P of a particle hitting a gas bubble in a solid is evaluated theoretically. This probability is found to depend neither on the energy of the particle, nor on the radius of the bubble. A simple expression of P is given in the case of a harmonic channeling potential. Then an experiment is described concerning α particles channeled along (111) planes in aluminium containing helium bubbles. In this particular case, the measured probabilitity (P=0.27+-0.09) is in good agreement with the corresponding theoretical values (0.34 for a harmonic potential and 0.24 for a more realistic potential)

On a dans un premier temps, calcule la probabilite de decanalisation p d'une particule en presence d'une bulle de gaz dans un cristal. Cette probabilite ne depend ni de l'energie de la particule ni du rayon de la bulle. On donne une expression analytique dans le cas ou le potentiel de canalisation est harmonique. Dans une deuxieme partie, on decrit une experience concernant des particules α canalisees le long de plan (111) d'aluminium et rencontrant des bulles d'helium. Pour ce cas particulier, on mesure une probabilite P egale a 0,27+-0,09, en bon accord avec la valeur theorique (0,24 ou 0,34 suivant le potentiel choisi)Files
