Possibilities of 14N(d,p0) nuclear reaction for surface analysis of nitrogen

Consideration is being given to the nuclear-physical method for measuring nitroqen impurities in steel using 14N(d, Po) reaction based on measuring reaction yields dependinq on deuteron enerqy in 0.8-2.0 MeV range. The function of impurity distribution with depth C(x) is assigned in the form of polynomial on x depth, which parameters are determined on the basis of experimental data by optimization method. Results of calculation of average < xsup(i) > values representing model parameters are given for C, AlN, Fe. Possibility of measuring surface nitrogen films of about monolayer thickness at the background of averaqe nitrogen concentration less than 10 -2 masg is shown. Experimental data on nitrogen distribution in a sample of 1Kh.)M steel are presented
