Hot nuclei in reactions induced by heavy projectiles, protons and antiprotons

International audienceLight projectiles like protons and antiprotons with several GeV kinetic energy enable avery efficient heating of nuclei, similar to what is routinely achieved in nucleus-nucleuscollisions. At the same time, the excitation of the collective modes in nuclei isminimized, making possible for the first time the study of the heat effects exclusively.The scarcity of muhifragmentaiion in antiproton induced reactions on heavy targetsseems to show that when such a phenomenon occurs in a nucleus-nucleus collisions ilis most likely driven by initial compression and angular momentum rather than heat
