Abstract

The energy spectra of neutrons emitted following radiative capture on ¹⁶O and ²⁸Si nuclei of negative pions at rest have been measured. There is some evidence in the ¹⁶O spectrum for a group of neutrons between 4 and 5 MeV which may correspond to decay of a giant resonance state, while both the ¹⁶O and ²⁸Si data have an excess of neutrons at the higher energies which may be due to direct emission of neutrons.

Development of organic scintillators
1979, Nuclear Instruments and Methods
The development of organic scintillators is reviewed with emphasis on work that has been reported since 1964. The scintillation process is discussed. Measurements of scintillator properties such as response-energy dependence, energy resolution, timing characteristics, pulse shape discrimination and scintillation anisotropy are reviewed. Some recent and novel applications of organic scintillators are noted.
