| 英文摘要 | Ratios of differential chemical potential values relative to the temperature, (mu(n) - mu(p))/ T, extracted from isotope yields of 13 reaction systems at 40 MeV/nucleon are compared to those of a quantum statistical model to determine the temperature and symmetry energy values of the fragmenting system. The experimental (mu(n) - mu(p))/ T values are extracted based on the modified Fisher model. Using the density value rho/rho(0) = 0.56 from the previous analysis, the temperature and symmetry energy values of T = 4.6 +/- 0.4 MeV and a(sym) = 23.6 +/- 2.1 MeV are extracted in a framework of a quantum statistical model. These values agree well with those of the previous work, in which a self-consistent method was utilized with antisymmetrized molecular dynamics simulations. The extracted temperature and symmetry energies are discussed together with other experimental values published in literature. |
