摘　　要：99MeV^(31)P离子通过金箔后的平衡电荷态分布在中国原子能科学研究院串列加速器的Q3D磁谱仪上进行了测量。同时,我们应用约化x^2分布拟合了重离子在箔上的非对称电荷态分布。在磷离子的K壳层和L壳层之间的边界处观察到了壳效应。Equilibrium charge state distribution of 99MeV 31P ions after the passage through gold foil have been measured by using Q3D magnetic spectrometer at CIAE tandem accelerator. Meanwhile, we applied the reduced chi-squared distribution for the fitting of asymmetric charge state distribution of heavy ions on foils. The shell effect was observed in the boundary charge state between 31P K-shell and L-shell.
