The invention relates to a method for processing electrical signals from a phoswich scintillator including an upstream scintillator and a downstream scintillator, characterized in that it includes, for each electrical signal: digitizing the electrical signal; determining an amplitude A and an integral surface S of the digitized electrical signal; and representing an event associated with an electrical signal by means of the data pair S1, S2 such that: S1 = [tau1/(tau2-tau1)] [A (tau2/tau0) - S], and S2 = [tau2/(tau2-tau1)] [S - A (tau1/tau0)] where: tau1 is a signal decay constant that is characteristic of a detection of a particle in the upstream scintillator; tau2 is a signal decay constant that is characteristic of a detection of a particle in the downstream scintillator; and tau0 is an integration constant selected for measuring the integral surface S. |
