Abstract
An extensive study is made of the use of sulphur as a monitor for neutrons with energies from 2 to 20 Mev. Irradiated disks of pressed sulphur are burnt before counting to increase the efficiency and reproducibility of determining the P32 activity. It was established that on burning irradiated sulphur 95.5 ± 0.5% of the P32 activity is retained with a reproducibility of ± 1.0%. Measurements of relative cross sections for the S32 (n,p) P32 reaction have been extended to 20.3 Mev using the T (d,n) He4 and D (d,n) He3 reactions to produce monoenergetic neutrons. Neutron production using Zr−T targets is examined as is the effect of extraneous neutrons from the D (d,np) D process on the S32 (n,p) reaction.
