Abstract
The double-differential cross sections (DDX) of α-particle emission from the reaction of 14.6 MeV neutrons with elemental nickel have been measured using a multitelescope system. The cross sections at sixteen reaction angles from 25° to 164.5° have been obtained. The angle-integrated spectrum and the angular distribution of α-particle emission have been deduced from the DDX. The total a-particle emission cross section was 102 ± 8 mb. The present result was compared with the evaluation of ENDF/B-VI and other measurements.
