摘要：

The stopping power of gold has been measured for antiprotons in the energy range 0.2-3 MeV using a novel time-of-flight technique. The antiproton stopping power is found to be less than half the equivalent proton stopping power near the electronic stopping power maximum. In the high-energy limit the two stopping powers merge.
