Influence of inelastic scattering on (n, 2n) cross-sections of Cl35 and K39

The cross-sections of the reactions Cl35 (n, 2n) Cl34g,m and K39 (n, 2n) K38g,m were determined; the results are 1.7; 7.6 and 5.1; 0.8 mb, respectively. The excitation function of the reaction K39 (n, 2n) K38g was measured in the neutron energy region 13.4–15 MeV. The discrepancy between the experimental (n, 2n) data and the values calculated on the basis of the statistical model can be explained by the actual spectrum shape of inelastically scattered neutrons.

Влияние неупругого рассеяния на поперечные сечения (n, 2n) Cl35 и К39


Определены поперечные сечения реакций Cl35(n, 2n)Cl34g,m и К39(n, 2n) К38g,m, для чего получены значения 1,7; 7,6 и 5,1; 0,8 мб соответственно. Функция возбуждения реакции К39 (n, 2n) К38g измерялась в интервале знергии нейтронов 13,4–15 Мзв. Отличие между зкспериментальными данными (n, 2n) и значениями, вычисленными на базе статистической модели, объясняются действительным спектральным распределением неупруго рассеянных нейтронов.
