Abstract

A low-background experimental arrangement for (γ, charged particle) reactions is described. Studies on the nature and sources of the background indicated that best results could be obtained through complete shielding, a paraffin lining in the scattering chamber, and the use of permanent magnets for electron sweeping. To demonstrate the capability of the system, a photoproton spectrum at 90° is presented for the 16O(γ, p)15N reaction.
