In the tables below, the first column is the projectile energy in keV, the second column is cross section in square Angstrom (10E-16 cm2) or the ratio between cross sections in permille (10E-3), and the last column gives the exp. uncertainty as twice the relative standard deviation, i.e. 2 sigma(X)/X.
