We report the stopping power of molecular hydrogen for antiprotons of kinetic energy above the maximum (approximately 100 keV) with the purpose of comparing with the proton one. Our result is consistent with a positive difference in antiproton-proton stopping powers above approximately 250 keV and with a maximum difference between the stopping powers of 21%+/-3% at around 600 keV.
我们报告了分子氢对于动能高于最大值（约100 keV）的反质子的阻止本领，目的是与质子的情况进行比较。我们的结果与大约250 keV以上反质子 - 质子阻止本领的正差异相一致，并且在约600 keV时阻止本领之间的最大差异为21%±3%。
