Measurement of the D(n,2n)p reaction cross section up to 30 MeV

This article presents a running experimental program to measure the neutron-induced deuteron break-up reaction between 5 and 10MeV, and between 20 and 30MeV. The measurements are performed with a C6D6 detector as deuteron target placed in a beam line of the Tandem 7MV accelerator at Bruy`ˆ atel, France, dedicated to the use of a4 π neutron detector which allows to measure the two emitted neutrons. This experimental work is done in parallel with an ab initio calculation of the reaction which is sum up in the text. Comparisons to the measured cross section are done together with CENDL2 and ENDF/B-VII evaluations.
