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 ⁵⁸Ni¹⁹⁺ 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).

用人 $p+{}^{58}\text{你}$弹性散射法测定95 MeV / u与氢气碰撞时⁵⁸ Ni ¹⁹⁺的K壳电离截面

我们提出了一种新的实验方法，用于测量低电荷离子与存储环中的氢气目标发生碰撞的内壳电离截面。该方法基于通过核上质子弹性散射的众所周知的微分截面的校准。在这项工作中，获得了95 MeV / u ⁵⁸ Ni ¹⁹⁺离子与氢原子碰撞的1047（100）谷仓的K壳电离截面。与实测电离截面相比，通过相对论电离码修改程序（RICODE-M）进行的预测获得了良好的一致性。
