“…10 Above 3 MeV, For #304 stainless steel, the primary constituents are chromium, iron, and nickel. For chromium, thick-target the 13 N activity from the 13 C(p, n) reaction exceeds the 12 C(p, g) activity even though the isotopic abundance yields for the (p, n) reaction on 52 Cr, calculated using cross sections from Refs. 16, 19, and 20, are presented of 13 C in natural carbon is only 1.1%.…”
