MEASUREMENT OF THE STOPPING POWER OF SILICON FOR ANTIPROTONS BETWEEN 0.2 AND 3 MEV

[摘要] Our previous measurement of the stopping power of silicon for antiprotons has been extended down to 200 keV. The antiproton stopping power is found to be more than 30% lower than that for equivelocity protons at 200 keV. The Z1(3) contribution to the stopping power (the Barkas effect) is deduced by comparing the stopping power for protons and antiprotons. Comparisons to theoretical estimates are made.
