Evaluation of neutron- and proton-induced nuclear data on Al-27 up tp 2 GeV

We have evaluated neutron and proton nuclear data of Al-27 for energies up to 2 GeV. The best set of optical model parameters were obtained from 20 Me V for neutrons and from reaction threshold for protons up to 250 MeV with t he phenomenological non-relativistic potential forms incorporating effects of the dispersion relationship and results of the Dirac phenomenology. The transmission coefficients for neutrons and protons derived from the optical models were fed into the GNASH code system to calculate angle-energy corre lated emission spectra for light ejectiles and gamma rays. For energies bet ween 250 MeV and 2 GeV, the total, reaction and elastic scattering cross se ctions were evaluated by an empirical fit and recent systematics. Emitted n ucleon and pion spectra were estimated by use of QMD+SDM (Quantum Molecular Dynamics+Statistical Decay Model).
