0030 // This code keep data for proton and neutron Barashenkov evaluation
0031 // for the total and reaction (inelastic) cross sections.
0032 // The elastic cross section is a difference sigma(el) = sigma(total) - sigma(inel).
0033 // The low-energy limit 14 MeV, high energy limit 1 TeV. Below energy limit
0034 // the cross sections at 14 MeV is used, above maximum energy a cross section
0035 // at 1 TeV is given.
