Measuring system of proton total reaction cross-sections at tandem energy region

Proton total reaction cross-sections of natSi and natAl have been measured by using a very simple attenuation technique. Energy range is 14–17MeV, which covers the threshold energy of 28Si(p,n). Features include well-defined beam and very low noise counters, elastic and inelastic scattering corrections. The energy dependence of total reaction cross-sections of natSi shows a resonance-like behavior just above the 28Si(p,n) threshold energy.
