Abstract
We report a cosmic-ray antiproton spectrum measured with the BESS balloon experiment performed in 2002, which was in an intermediate period between the solar maximum in 2000 and the coming solar minimum. The observed antiproton spectrum and the antiproton to proton ratio are crucial for further development of the drift model of the solar modulation effect which has been generally supported by the previous measurements.
