A study of the phase transition in the usual statistical model for nuclear multifragmentation
S. Das Gupta, A. Z. Mekjian
We use a simplified model which is based on the same physics as inherent in most statistical models for nuclear multifragmentation. The simplified model allows exact calculations f…
Off-shell effects in dilepton production from hot interacting mesons
Song Gao, Charles Gale
The production of dielectrons in reactions involving a_1 mesons and pions is studied. We compare results obtained with different phenomenological Lagrangians that have been used in…
The lattice gas model with isospin-dependent interactions
J. Pan, S. Das Gupta
In this paper we continue the investigation of the lattice gas model. The main improvement is that we use two strengths for bonds: one between like particles and another between un…
First Order Phase Transition in Intermediate Energy Heavy Ion Collisions
J. Pan, S. Das Gupta, M. Grant
We model the disassembly of an excited nuclear system formed as a result of a heavy ion collision. We find that, as the beam energy in central collisions in varied, the dissociatin…
Caloric Curve for Finite Nuclei in Thomas-Fermi Theory
J. N. De, S. Das Gupta, S. Shlomo +1
In a finite temperature Thomas-Fermi theory with realistic nuclear interactions, we construct caloric curves for finite nuclei enclosed in a sphere of about times the norma…
