摘要：

We report the stopping power of molecular hydrogen for antiprotons of kinetic energy above the maximum (approximate to100 keV) with the purpose of comparing with the proton one. Our result is consistent with a positive difference in antiproton-proton stopping powers above approximate to250 keV and with a maximum difference between the stopping powers of 21%+/-3% at around 600 keV.
