提出了一种测量储氢环中低荷电离子与氢气靶碰撞的内壳电离截面的新实验方法。该方法基于质子在原子核上弹性散射的微分截面标定。得到了95 MeV/u Ni-58（19+）离子与氢原子碰撞时1047(100)barn的k壳电离截面。与实测电离截面比较，结果与相对论电离码修正程序（RICODE-M）的预测结果吻合较好。
We present a new experimental method for measuring inner-shell ionization cross sections of low-charged ions colliding with hydrogen gas target in a storage ring. The method is based on a calibration by the well-known differential cross sections of proton elastic scattering on nuclei. K-shell ionization cross section of 1047(100) barn for the 95 MeV/u Ni-58(19+) ions colliding with hydrogen atoms was obtained in this work. Compared to the measured ionization cross section, a good agreement is achieved with the prediction by the Relativistic Ionization CODE Modified program (RICODE-M).
