Abstract
Cosmic ray antiprotons were first detected 3 years ago by Golden et al. (1979) and Bogomolov et al. (1979). The measured flux at ~ 10 GeV was found to be a factor of 5 to 10 higher than expected in the leaky box model. More recently, an unexpected high antiproton flux has been measured by Buffington et al. (1981) at ~ 200 MeV, well below a low energy cut-off in the spectrum expected if the antiprotons are secondary. Here, we review briefly calculations of the flux of secondary antiprotons expected for different models of cosmic ray propagation and also disucss some of the primary origin hypotheses which have been proposed to account for the data.
