Abstract

Profiting from previous works done with the \emph{INDRA} multidetector on the description of the light response $\mathcal L$ of the CsI(\emph{Tl}) crystals to different impinging nuclei, we propose an improved $\Delta E - \mathcal L$ identification-calibration procedure for Silicon-Cesium Iodide (Si-CsI) telescopes, namely an Advanced Mass Estimate (\emph{AME}) method. \emph{AME} is compared to the usual, %$"\Delta E - E"$ simple visual analysis of the corresponding two-dimensional map of $\Delta E - E$ type, by using \emph{INDRA} experimental data from nuclear reactions induced by heavy ions in the Fermi energy regime. We show that the capability of such telescopes to identify both the atomic $Z$ and the mass $A$ numbers of light and heavy reaction products, can be quantitatively improved thanks to the proposed approach. This conclusion opens new possibilities to use \emph{INDRA} for studying these reactions especially with radioactive beams. Indeed, the determination of the mass for charged reaction products becomes of paramount importance to shed light on the role of the isospin degree of freedom in the nuclear equation of state.
