Gamma rays resulting from nonelastic processes of 14·2 MeV neutrons with sodium, magnesium, silicon, sulphur, titanium, chromium and iron

Abstract

Gamma rays resulting from the interaction of 14·2 MeV neutrons with ²³Na, ²⁴Mg, ²⁸Si, ³²S, ⁴⁸Ti, ⁵²Cr and ⁵⁶Fe were investigated. The incident neutrons were produced by means of the T(d, n)⁴He reaction. The associated-particle time-of-flight technique was used to discriminate between the neutrons and the gamma rays resulting from the nonelastic scattering processes. The differential gamma-ray production cross-sections were measured for gamma rays with energies of 0·44, 0·64, 1·27, 1·63 MeV for ²³Na; for a gamma ray with energy of 1·37 MeV for ²⁴Mg; for a gamma ray with energy of 1·78 MeV for ²⁸Si; for gamma rays with energies of 1·27, 2·06, 2·24 MeV for ³²S; for gamma rays with energies of 0·99 and 1·31 MeV for ⁴⁸Ti; for gamma rays with energies of 0·93, 1·33, 1·43 MeV for ⁵²Cr; for gamma rays with energies of 0·85 and 124 MeV for ⁵⁶Fe. The integrated gamma ray production cross-sections were also deduced.
