Abstract

Cosmic-ray low-energy antiproton and proton spectra were measured in a transient period of solar field reversal. Expansion of solar wind is the cause of the solar modulation of cosmic rays. The results showed an increase of the antiprotons/protons flux ratio following the solar magnetic field reversal and it generally agrees with a drift model of the solar modulation.
