| dc.description | Using an isospin- and momentum-dependent transport model we study near-threshold pion production in heavy-ion collisions induced by radioactive beams at the planned Rare Isotope Accelerator (RIA). We revisit the question of probing the high density behavior of nuclear symmetry energy $E_{sym}(ρ)$ using the $π^-/π^+$ ratio. It is found that both the total and differential $π^-/π^+$ ratios remain sensitive to the $E_{sym}(ρ)$ when the momentum-dependence of both the isoscalar and isovector potentials are consistently taken into account. Moreover, the multiplicity and spectrum of $π^-$ mesons are found more sensitive to the $E_{sym}(ρ)$ than those of $π^+$ mesons. Finally, effects of the Coulomb potential on the pion spectra and $π^-/π^+$ ratio are also discussed. | |
