TL;DR: In this paper, the INDRA multidetector was used to study multifragmentation processes in central collisions for the Xe + Sn reaction at 50 A MeV, and the fragment kinetic energy spectra indicated a fast disintegration of the system with a radial collective motion of about 2 A MEV.

TL;DR: The 4π array INDRA was used to detect nearly all charged products emitted in Ar + Ni collisions between 52 and 95 MeV/u as mentioned in this paper, and the charge, mass and excitation energy E ∗ of the quasi-projectiles have been reconstructed event by event.
