Nuclear slab collision in a relativistic quantum field theory

PDF Version Also Available for Download.

Description

The relativistic mean field model proposed by J.D. Walecka was recently used with great success to describe the properties of nuclear matter as well as the structure of the finite static nuclei. Starting from Walecka's Lagrangian the nucleons are represented by single particle spinors, which are determined by a Dirac equation containing a repulsive mean neutral vector field V/sub ..mu../ and an attractive mean isoscalar field sigma. Both fields satisfy Klein-Gordon equations. Their source terms are again determined by the spinors. This relativistic mean field model was applied to the dynamics of two colliding slabs. They are translational invariant in ... continued below

Description

The relativistic mean field model proposed by J.D. Walecka was recently used with great success to describe the properties of nuclear matter as well as the structure of the finite static nuclei. Starting from Walecka's Lagrangian the nucleons are represented by single particle spinors, which are determined by a Dirac equation containing a repulsive mean neutral vector field V/sub ..mu../ and an attractive mean isoscalar field sigma. Both fields satisfy Klein-Gordon equations. Their source terms are again determined by the spinors. This relativistic mean field model was applied to the dynamics of two colliding slabs. They are translational invariant in two transverse dimensions and consist of spin and isospin symmetric nuclear matter. By specification of appropriate initial conditions for the collision of two equal slabs, the system of coupled Klein-Gordon-Dirac equations was solved for lab bombarding energies per nucleon up to 400 MeV. At low energies the results are identical with TDHF results. The damping of the collision, the phenomenon of high nuclear density, and the effect of retardation during the reaction are studied.
