用$π^-/π^+$比探测对称能密度区的确定
Determination of the density region of the symmetry energy probed by the $π^-/π^+$ ratio
摘要：
在日本放射性同位素束流装置（RIBF）进行的300 MeV/核子的$^{132}$ Sn+ $^{124}$ Sn反应中，几种独立方法的研究一致表明，$π^-/π^+$比值只是探测饱和密度附近的对称能。
英文摘要：
The studies, from several independent methods, consistently show that $π^-/π^+$ ratio in the $^{132}$Sn+$^{124}$Sn reaction at 300 MeV/nucleon, which is being carried out at Radioactive Isotope Beam Facility (RIBF) in Japan, just probes the symmetry energy around saturation density.
