Negative heat capacity in the critical region of nuclear fragmentation: an experimental evidence of the liquid-gas phase transition
M. D'Agostino,Francesca Gulminelli,Ph. Chomaz,M. Bruno,F. Cannata,R. Bougault,F. Gramegna,I. Iori,N. Le Neindre,Giacomo Vito Margagliotti,A. Moroni,G. Vannini +11 more
TL;DR: In this paper, an experimental indication of negative heat capacity in excited nuclear systems is inferred from the event by event study of energy fluctuations in Au quasi-projectile sources formed in Au+Au collisions at 35 A.MeV.

TL;DR: In this article, a 1-parameter fitting procedure is proposed to extract information on the particle type and energy, and the performance of this method in terms of energy resolution and n=g discrimination is analyzed, together with the capability to identify and resolve pile-up events.
