Activation Cross Sections with 14 MeV Neutrons

Some activation cross sections have been measured for the elements Na, Al, Sc, Cr, Cu, Ag and Bi using 14.8 MeV neutrons from the (DT) reaction. The cross section values with their experimental errors are as follows:

²³Na(n, p)²³Ne 29 mbn ± 10%, ²³Na(n, α)²⁰F 222 mbn ± 10%, ²⁷Al(n, p)²⁷Mg 77 mbn ± 10%, ⁴⁵Sc(n, 2n)^44mSc 149 mbn ± 15%, ⁴⁵Sc(n, 2n)⁴⁴Sc 179 mbn ± 15%, ⁴⁵Sc(n, α)⁴²K 63 mbn ± 15%, ⁵⁰Cr(n, 2n)⁴⁹Cr 32 mbn ± 10%, ⁵²Cr(n, p)⁵²V 105 mbn ± 10%, ⁶⁵Cu(n, p)⁶⁵Ni 29 mbn ± 10%, ¹⁰⁷Ag(n, 2n)¹⁰⁶Ag (8.2 days) ~6500 mbn, ¹⁰⁷Ag(n, 2n)¹⁰⁶Ag (24 min) 662 mbn ± 10%, ¹⁰⁹Ag(n, 2n)¹⁰⁸Ag 833 mbn ± 10%, ¹⁰⁹Ag(n, p)¹⁰⁹Pd 2.7 mbn ± 20%, ¹⁰⁹Ag(n, α)¹⁰⁶Rh 12 mbn ± 25%, ²⁰⁹Bi(n, p)²⁰⁹Pb 0.7 mbn ± 15%, ²⁰⁹Bi(n, α)²⁰⁶T1 0.6 mbn ± 15%. The cross sections were measured in relation to 556 mbn for the cross section of ⁶³Cu(n, 2n)⁶²Cu and 117 mbn for the cross section of ²⁷Al(n, α)²⁴Na reactions. It has been found that the (n, α) cross section values follow more or less the empirical curve given by Blosser, Goodman and Handley in 1958.
