Accurate accelerator energy calibration using selected resonances in proton elastic scattering and in (p,gamma) and (p,p'gamma) reactions

• The present work aims at contributing to the field of Ion Beam Analysis by providing a set of standard, high-accuracy nuclear resonance reaction data points to be used for accelerator energy calibration up to 4.6 MeV, more specifically with the use of the Al-27(p,gamma),C-13(p,gamma), C-12(p,p(0)) and S-32(p,p'gamma) resonant reactions, as a result of a comprehensive investigation in two different laboratories. The use of resonances at higher energies, namely up to 6 MeV, is also discussed. The measurements have been performed at two different electrostatic accelerators, namely at the 5.5 MV HV TN-11 of NCSR "Demokritos", Greece, and at the 5 MV 15SDH-2 Pelletron Tandem accelerator at Uppsala University in Uppsala, Sweden. Common points were used to normalize and validate the data. The possible use of the O-16(p,p(o)) resonance at 3.47 MeV is also discussed and analyzed. (C) 2017 Elsevier B.V. All rights reserved.
