A flux of neutrons is required to make strain measurements in crystalline materials. At ISIS facilities, neutrons are produced by accelerating protons and firing these high-energy protons onto a high atomic mass target, which causes the target nuclei to be elevated to a highly excited state, ...
Simulation of protons and deuterons produced in nuclear muon captures relies on their inclusive yields in Al reported in Refs. [29,30]. As there are no published neutron spectra on Al, the simulation of neutrons relies on the neutron spectrum on Ca [31] and assumes 1.2 neutrons emitted per...
