Description
The paper gives results of measurements of the double-differential neutron scattering cross-sectioln for reactor graphite for temperatures of 15, 490, 1000 and 1370°C. The measurements were made at the WWR-M reactor with an experimental device intended for studying the inelastic scattering of slow neutrons. Monochromatization and chopping of the primary neutron beam were achieved with the aid of a single crystal and a mechanical chopper. The scattered radiation is analysed in terms of energy using the time-of-flight method simultaneously for eight angles in the range 10°- 115°. The data obtained are represented in the form of the scattering cross-section S(ϵ, K), which is compared with the result of calculations based on the frequency spectrum suggested by Egelstaff.

Abstract (Russian)
Predstavleny rezul'taty izmerenija dvazhdy differencial'nogo sechenija rassejanija nejtronov dlja reaktornogo grafita dlja temperatur: 15, 490, 1000 i 1370°S. Izmerenija provedeny na reaktore VVR-M na jeksperimental'noj ustanovke, sozdannoj dlja izuchenija neuprugogo rassejanija medlennyh nejtronov. Monohromatizacija i preryvanie pervichnogo puchka nejtronov osushhestvljaetsja s pomoshh'ju monokristalla i mehanicheskogo preryvatelja. Rassejannoe izluchenie analiziruetsja po jenergii metodom vremeni proleta odnovremenno pod vosem'ju uglami v intervale 10°- 115°. Poluchennye dannye predstavleny v vide sechenija rassejanija S(ϵ, K), kotoroe sravnivaetsja s rezul'tatami raschetov, vypolnennyh na osnove chastotnogo spektra, predlozhennogo Jengel'staffom.
