In the Fermi energy domain, it is extremely complex to experimentally isolate fragments and particles emitted by a hot nucleus produced during a heavy ion collision. This article presents a new method to characterize more precisely hot quasiprojectiles. It tries to take into account as accurately as possible the distortions generated by all the other potential participants of the nuclear reaction. It is quantitatively shown that this method is an improvement compared to a “classical calorimetry” used with a 4π detector array.
