An annular /sup 227/Ac-be isotopic neutron source, containing 6.6-Ci / sup 227/Ac, is described for application in fast and thermal neutron activation analysis, with high accuracy, for major constituents in ores, alloys and industrial concentrates. The characteristics of the neutron output and of the fast, epithermal and thermal flux, and flux gradients are described in detail. The determination of manganese in pyrolusite ores and ferro-manganese is compared to results obtained previously with a cylindrical 1-Ci /sup 226/Ra--Be soarce. Two new sources of systematic errors have been discovered. (auth)
