Measurement of the neutron spectrum of the 51V(p,n)51Cr reaction at 1585 keV

Neutron production by 51V(p,n)51Cr reaction close to the reaction threshold is interesting for its pure production of neutrons at low kiloelectronvolts. In this work, for the first time, the angle-dependent neutron spectrum is measured close to the threshold, particularly at 1585-keV proton energy only 20 keV above the reaction threshold. The experiment was performed at the MONNET facility (JRC Geel), employing the Time-Of-Flight technique and a thick Vanadium target. The 7Li(p,n)7Be reaction near the threshold was also measured and used as a reference and in a neutron transmission measurement for self-absorption correction. The angular-dependent energy spectra for the 51V(p,n)51Cr have been obtained and the integrated energy spectrum is presented. Their resulting spectrum reveals a pronounce peak at (6.49 ± 0.04) keV.
