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