| 英文摘要 | AbstractWe study the problem of π production in heavy-ion collisions in the context of the isospin-dependent Boltzmann–Uehling–Uhlenbeck transport model. We generated nucleon densities using two different models, the Skyrme–Hartree–Fock (SHF) model and the configuration interaction shell model (SM). Indeed, inter-nucleon correlations are explicitly taken into account in SM, while they are averaged in the SHF model. As an application of our theoretical frameworks, we calculated the π? and π+ yields in collisions of nuclei with A = 30–40 nucleons. We used different harmonic oscillator lengths bHO to generate the harmonic oscillator basis for SM in order to study both theoretical and experimental cases. It is found that the SM framework with bHO = 2.5?fm and SHF can be distinguished by the yield of π mesons, in this case the density distribution calculated by the SM produces more π in the collision. In comparison, SM with bHO = 2.0?fm is distinguished from SHF by the double π?/π+ ratios with different large impact parameters, from which one can find that the double π?/π+ ratios of SM change smoother and are less than those of SHF. |
