Analysis of response data for several organic scintillators

Abstract

Data on the scintillation response (light output) of anthracene, stilbene, NE-213, NE-102 and Pilot-B to electrons and protons and of Ne-230 to electrons and deuterons reported recently by Smith et al. 1) have been fitted by the method of least squares to the L(E) = S ∫ 0 E dε[1+kB( dE dx +C dE dx ) 2] −1 where E is the initial particle energy, d E/d x is the specific energy loss, and S, kB and C are the adjustable parameters. Required values of d E/d x were computed from available data 16,17). Scintillation efficiencies S were deduced from the electron data for which d E/d x≈0. One-parameter ( kB variable, C = 0) and two-parameter ( kB and C variable) fits for the heavy-particle data were obtained and compared with other results reported in the literature.
