Multifragmentation of spectators in relativistic heavy-ion reactions
A. S. Botvina,Igor Mishustin,M.L. Begemann-Blaich,J. Hubele,G. Imme,I. Iori,P. Kreutz,Gerd Joachim Kunde,W. D. Kunze,Volker Lindenstruth,U. Lynen,A. Moroni,W. F. J. Müller,C. A. Ogilvie,J. Pochodzalla,G. Raciti,Th. Rubehn,H. Sann,A. Schüttauf,W. Seidel,W. Trautmann,A. Wörner +21 more
TL;DR: In this article, the authors used the ALADIN forward-spectrometer at SIS to study multi-fragment decays of 197 Au projectiles after collisions with C, Al, Cu and Pb targets at a bombarding energy of 600 MeV.
Journal ArticleDOI
Thermodynamical features of multifragmentation in peripheral Au + Au Collisions at 35 A.MeV
M. D'Agostino,A. S. Botvina,M. Bruno,Aldo Bonasera,J.P. Bondorf,R. Bougault,P. Désesquelles,P. Désesquelles,E. Geraci,Francesca Gulminelli,I. Iori,N. Le Neindre,Giacomo Vito Margagliotti,I. N. Mishustin,A. Moroni,A. Pagano,G. Vannini +16 more
TL;DR: In this paper, the distribution of fragments produced in events involving the multifragmentation of excited sources is studied for peripheral Au + Au reactions at 35 A MeV and an isotropic emission in its rest frame has been observed, indicating that an equilibrated system has been formed.
Journal ArticleDOI
Multifragment break-up of nuclei by intermediate-energy protons
TL;DR: In this article, a cascade-fragmentation-evaporation (CFE) model of proton-nucleus reactions at intermediate energies is developed within the framework of this model, and a systematic analysis has been performed of a broad set of data on nuclear fragmentation induced by protons with energies E p ≈ 1-100 GeV.
Journal ArticleDOI
Thermodynamical features of multifragmentation in peripheral Au + Au Collisions at 35 A.MeV
M. D'Agostino,A. S. Botvina,M. Bruno,Aldo Bonasera,J.P. Bondorf,I. N. Mishustin,Francesca Gulminelli,R. Bougault,N. Le Neindre,P. Desesquelles,E. Geraci,A. Pagano,I. Iori,A. Moroni,Giacomo Vito Margagliotti,G. Vannini +15 more
TL;DR: In this paper, the distribution of fragments produced in events involving the multifragmentation of excited sources is studied for peripheral Au + Au reactions at 35 A.MeV and a temperature 4 - 6 MeV, depending on the freeze-out hypothesis.
Journal ArticleDOI
Statistical approach for supernova matter
TL;DR: In this paper, a statistical approach for description of nuclear composition and equation of state of stellar matter at subnuclear densities and temperature up to 20 MeV was proposed, which is expected during the collapse and explosion of massive stars.
