[en] The range R distribution g(α, R) of particles having lost an amount α of energy is connected with the energy epsilon distribution h(R, epsilon) of particles passing through a thickness R of thin absorber. In order to obtain the moments of g(α, R), we must solve a Fredholm integral equation of the second kind

On etudie la densite de probabilite g(α, R) du parcours R associe au depot d'une energie α et la connexion avec h(R, epsilon), densite de probabilite de la perte d'energie epsilon relative a un parcours R. Le calcul des moments de g(α, R) revient a la resolution d'une equation integrale de Fredholm de seconde especeJournal

[en] It is considered the problem of neutron absorption by a slab of absorbing and multiplying medium, within the framework of the theory of birth and death process. The number of transmitted neutrons is a random variable the probability of which is a solution of Chapman-Kolmogorof equations
