PROTON SIMULATION OF DISPLACEMENT EFFECTS INDUCED IN METALS BY 14-MeV NEUTRONS.

“…Equations (11), (13), and (14) define dcr R /dE at any value of E for known values of T , n, <J D , and F. n rx For calculating the PKA spectrum re sulting from nonelastic events we may assume the particle emission to be iso tropic. While this is not rigorously true for pre-equilibrium emission, the effect on the PKA spectrum of the departure from isotropic emission is negligible.…”
