Abstract
Differential cross sections have been measured for the elastic scattering of ${\mathrm{N}}^{14}$ from ${\mathrm{C}}^{12}$, ${\mathrm{N}}^{14}$ from ${\mathrm{N}}^{14}$, and ${\mathrm{C}}^{12}$ from ${\mathrm{C}}^{12}$ to a relative precision of about 5%, and an absolute accuracy of 15%. Incident energies of nominally 10 Mev/amu were employed, and an angular range was covered from approximately 4\ifmmode^\circ\else\textdegree\fi{} to 24\ifmmode^\circ\else\textdegree\fi{} in the center-of-mass system. The use of solid-state detectors rendered energy resolution of the order of 1.5%. Theoretical cross sections calculated from both the simple-diffraction model and the sharp-cutoff model were fitted to the experimental data, giving interaction radii for the three reactions of 6.44, 6.68, and 6.23 fermi, respectively.
