The absolute efficiency T013200100010 was +-0.6% at an average energy of 500 keV . T013200100011 The detector response was constant to better than T013200100012 1% from a few keV to 1 MeV and to 7% from 1 to 5 MeV.

(p,n) yields from the minor Sn isotopes in the T013200100026 target. T013200100027 The nonlinearities made it necessary to convert the T013200100028 observed average cross section to a cross section at T013200100029 an average beam energy.

T013200100046 For proton energies above 4 MeV, the systematic and T013200100047 random uncertainties combine in quadrature to give T013200100048 <1%. Below 4 MeV, the uncertainties are larger T013200100049 because of the decreasing ratio of yield to T013200100050 background.
