A γ-ray detection system of nearly 100% efficiency is described allowing analytical techniques such as nuclear reaction analysis (NRA), nuclear resonance reaction analysis (NRRA) and deuteron induced γ-ray emission (DIGME) to be performed with a minimum of beam induced sample damage. Using this system together with ion beams of low energy spread and narrow resonances at sub-Coulomb energies, NRRA can be performed with a depth resolution of about 1 nm in the surface region of a sample. The energy scanning of the accelerator and the data acquisition are performed by a computer controlled system.
