R-matrix parameters evaluation for direct and indirect kinematics data using AZURE2

Abstract R-matrix analyses, using the code AZURE2, were performed for the 12 C+ p resonant scattering data obtained in direct and inverse kinematics. Proton energy spectra in the region of the first three excited states in 13 N above the 12 C+ p threshold were analyzed. We used two kinds of statisti...

Summary:Abstract R-matrix analyses, using the code AZURE2, were performed for the 12 C+ p resonant scattering data obtained in direct and inverse kinematics. Proton energy spectra in the region of the first three excited states in 13 N above the 12 C+ p threshold were analyzed. We used two kinds of statistics data treatment to evaluate the uncertainties of the energy and widths parameter of the resonances obtained from direct and inverse kinematics spectra. Both methods indicate smaller width uncertainties from analyses of the inverse kinematics data. The correlation coefficients between resonance widths differ considerably for the direct and inverse kinematics or when analyzing direct and inverse kinematics data simultaneously.
