Abstract

The absolute cross sections for the competing reactions

{Na}^{23} (n, p) {Ne}^{23}

and

{Na}^{23} (n, α) F^{20}

have been measured over the energy range 4 to 19 Mev by the activation method using neutrons from the

H^{2} (d, n) {He}^{3}

N^{14} (d, n) O^{15}

C^{14} (d, n) N^{15}

, and

H^{3} (d, n) {He}^{4}

reactions. The excitation curves thus obtained are compared with theoretical results based upon the statistical theory. A fair fit is obtained for the (

n, p

) reaction, but serious discrepancies exist between the measured and calculated (

n, α

) cross sections.
