The transmission of a spherical shell of enriched B/sup 10/ was measured and used to determine the average energy of neutrons from a spherical antimony- beryllium source. Analysis of the transmission data in terms of the known absorption and total cross sections of B/sup 10/, including effects of single and multiple neutron scattering in the shell and source, permitted determination of the effective energy of neutrons in the shell, the average energy of neutrons emitted from the particular source, and an estimate of the initial antimony- beryllium photoneutron energy. The average energy of neutrons from the neutron source was 24.0 plus or minus 2.2 kev; the initial energy of the primary group of antimonyberyllium photoneutrons was 24.8 plus or minus 2.4 kev. A discussion of the source neutron energy as a function of source dimensions is included. (auth)
