Abstract
The importance and present needs of proton cross-section data of nitrogen needed by the Ion Beam Analysis (IBA) community are briefly reviewed. Previous experimental data presently used for the theoretical determination of the proton cross-sections are discussed. The Azure code based on the R-matrix formalism was then used to evaluate the data and to determine the nitrogen cross-section in the previous and presently desired angular domain and energy region of interest. The experimental elastic backscattering cross-section data, as spectra, for back-scattering analysis determined at angles in the laboratory frame of reference, theta(i,lab), of 165 degrees, 170 degrees, and 176 degrees are presented.
