The Boltzmann-Nordheim-Vlasov (BNV) equation has been solved by using a microscopic momentum-dependent (MD) nuclear mean field. This potential has been calculated in the framework of the self-consistent Brueckner theory up to the second order in the G-matrix. Comparison with the so-called soft and stiff Equation of State (EOS) is presented, using the Skyrme force. Calculations have been performed for the93Nb +93Nb reaction at Elab = 100, 250, 400 A MeV. Our results show that the subthreshold π0 production cross-section is very sensitive to the momentum-dependent mean field, resulting, at the lowest energy, in a total cross-section a factor of 7 larger than that obtained with a local potential. The effect decreases as the bombarding energy increases. [ABSTRACT FROM AUTHOR] |
