Abstract

The dependence of the CsI(Tl) scintillation time constants and intensities on the particle ionization profile is at the basis of the Charge and Mass identification technique for Light Charged Products in Intermediate Energy Nuclear Physics multi-detector arrays. The possibility of storing the digitized waveforms in true beam experiments allows performing further offline analyses and makes available a data set related to the interaction of different particle types in a wide energy range. We propose the direct least-square fitting of the baseline subtracted output waveforms as a method for the determination of the four-vector defining the CsI(Tl) scintillator light output as a function of the particle energy, mass and charge. In the present work we investigate the dependence of the four-vector on the energy deposited in the CsI(Tl) crystal in the range 10 MeV-240 MeV for isotopes with Z <= 5and also for ions with Z = 6-with no isotopic dependence-through the analysis of the waveform data set acquired with the CHIMERA 4 pi Multidetector in an experiment with a 21.5 MeV/u(20) Ne beam bombarding a C-12 target.
