Abstract

In order to measure pions in the range 10–30 MeV from the reaction 12C(γ, π+)12B∗ using monochromatic photons, for a study of excited collective spin-isospin analog states [1], a detection system for positive pions, which reduces the backgrounds from electrons and protons by very large factors, was developed. The techniques and detectors used, namely a ΔE - E plastic scintillation telescope with separate photomultipliers and a glued triple sandwich of CaF2-plastic-CaF2 scintillators, are described here.
