Open publisher page 0 citations

Abstract

A method is given for distinguishing between different charged particles as products of a nuclear reaction. It is based on the total energy loss and is suitable for singling out particles with the largest specific ionization, e.g., alpha particles. In this method, scintillation crystals are cut or evaporated to the thickness sufficient to stop particles of a given type and energy. A 270-mg/ cm/sup 2/ NaI(Tl) crystal and a 20-mg/cm/sup 2/ CsI(Tl) crystal prepared in this way were used for the energy spectra of deuteron bombardment of aluminum at 15 Mev and the O/sup 16/(n, alpha )C/sup 13/ reaction at 14.5 Mev, respectively. (D.L.C.)
