The distributions in water of indium resonance and 115In(n,n′)115m In neutrons from a 2.85-MeV T( ρ ,n)3 He source have been measured. The values of the integrated plane activities perpendicular to the proton beam direction (including the extrapolated region beyond the range of measurement in each plane) are presented. The experimental results are in agreement with Monte Carlo calculations utilizing two oxygen elastic-scattering descriptions and agree within quoted standard deviations in both cases.
