Nitrogen analysis using energetic ion beams

Measurement and parametrization of proton elastic scattering cross sections for nitrogen

“…The parametrization of the experimental data within physical approach provides a possibility to interpolate/extrapolate the 14 Experimentally obtained excitation functions are in good agreement with theoretical predictions especially for 150°and 165°in the entire energy region where calculations were preformed.…”

“…In the entire investigated energy region the cross sections are significantly higher than Rutherford. [4][5][6][7][8]14 Cross sections at 118°are compared with data from Ref. The uncertainty in the measured cross sections is calculated to be less than 6% for energies below 4.6 MeV and between 6% and 8% for energies from 4.6 to 5 MeV for 165°and 150°.…”

“…[4][5][6][7][8][9][10][11][12][13][14] In works published almost half a century ago, authors used gaseous N target and CsI͑Tl͒ crystal detectors to study states in compound nucleus 15 O. [10][11][12][13][14] For detection, silicon surface barrier detectors were applied at scattering angles important for the backscattering analysis. [10][11][12][13][14] For detection, silicon surface barrier detectors were applied at scattering angles important for the backscattering analysis.…”

Elastic Backscattered Cross-Sections of 14n(p,p0)14n at High Angles

“…The maximum angle of the silicon surface barrier detector, used to detect backscattered particles, to the incident beam at the Materials Research Group, iThemba LABS is 176 o [8]. Proton backscattered cross section data at this angle and in the preferred E i (2000, say, to 3000) were needed since literature search [3,[9][10][11][12][13][14][15][16][17], and the evaluation of these data by [18] has shown that these experimental cross sections did not exist and that in various energy range, E i , there exist significant differences in the cross-sections. These differences are shown in Fig.…”
