摘要
Data on the absolute light output L(E) of plastic scintillator, in equivalent electron energy, to protons with energies up to 20 MeV have been fitted with the parameterization L(E) = A integral(0)(R) ln[+ alpha(dE/dx)](dx), where E is the initial particle energy, dE/dx is the specific energy loss, R is the particle range, and alpha is the only free parameter. The scaling factor A has been expressed in terms of alpha and the specific energy loss for a minimum ionizing particle, producing an absolute response curve. The best-fit value was determined to be alpha = (0.025+/-0.002) g cm(-2)MeV(-1) which gives a normalization of A = 41.0 MeV/(g/cm(2)). The results of the parameterization were compared with absolute response data for protons up to 150 MeV, and deuterons up to 120 MeV, with excellent agreement being observed.
