Scintillation intensity of NE-102A screens: Numerical integration of an expression for the radioluminescence yield, eventual application as a method of particle identification

The function S(E) of luminescence intensity of NE-102A scintillator irradiated by ionizing particles, in the energy range form 0.2 to 20 MeV, is studied by means of numerical integration of an expression already developed for specific luminescence, dS/dx. Good agreement is observed between calculated curves and experimental results obtained by us and by other authors, with α-particles (1.75-5.28 MeV) and protons (0.5-10.0 MeV). An identification method for ionizing particles of charge +1 at low energies (below 1.5 MeV), based only on measurements of energy and total and delayed luminescence, is suggested. (orig.)
