M. Moszynski et al., PARTICLE IDENTIFICATION BY DIGITAL CHARGE COMPARISON METHOD APPLIED TO CSI(TL) CRYSTAL COUPLED TO PHOTODIODE, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 336(3), 1993, pp. 587-590
The application of the high energy resolution technique to the digital
charge comparison method of particle identification with a CsI(Tl)-ph
otodiode assembly allowed to get a good alpha-proton separation down t
o about 2 MeV alpha particles.
