Nuclear Collisions Modeled with a Simple Piston-gas Model

Main Article Content

Mario J. Pinheiro


A simple one-dimensional gas-piston kinetic model gives the interaction potential between two colliding heavy ions. In the frame of the classical, thermodynamical approach, the colliding heavy ions are not submitted to friction, but produces an irreversible phenomena with cause at the difference of pressure p“felt” by the nucleon gas when ions collide with the target when compared with the pressure that nuclear matter exert on their boundaries when in thermodynamical equilibrium, and offers a straightforward way to calculate interacting potentials. Although this study neglect the Coulomb and nuclear nucleon-nucleon interactions form of the ion-ion potential at large and small distances between ions, the proposed approach may be applied for evaluation of the friction influence on the dynamics of ion-ion collisions.
