Spectromètre pour l'étude des réactions (n, a) à 14 MeV

A spectrometer has been constructed for the study of (n, α) reactions at 14 MeV, By detecting the 4He particle associated with neutron production, it is possible to measure the a time-of-flight in addition to the residual energy and energy loss, as measured by a telescope comprising a semiconductor detector and two proportional counters. The differential cross-section for the reaction 12C(n,α0)9Begs has been measured for several angles.
