Title: Analysis of states in {sup 13}C populated in {sup 9}Be + {sup 4}He resonant scattering

Abstract

Measurements of {sup 9}Be + {alpha} resonant scattering have been performed using the thick-target approach with a {sup 4}He gas volume and a large-area silicon strip detector. {sup 9}Be beam energies in the range 12 to 21.4 MeV were used to measure the {sup 13}C excitation energy spectrum between 13.2 and 16.2 MeV. An R-matrix analysis has been performed to characterize the spins and widths of {sup 13}C resonances, some of which have been proposed to be associated with a 3{alpha}+n molecular band.
