| Abstract: | The measured 7Li(p,n), and 6Li(n,p) cross sections at 0° show a high-energy peak (≈25 MeV/c FWHM) which we attribute primarily to nuclear charge exchange leading to final states in 7Be, 6Be, and 6He, respectively. By contrast, the 7Li(n,p) cross section at O° shows a broad weak high-energy peak believed due mostly to break-up processes. At 16°, the 6,7Li(n,p) cross sections are dominated by quasi-elastic scattering. |
