Relative abundance of antiprotons and antihelium in the primary cosmic radiation

Nature volume 274, pages 137–139 (1978)Cite this article

Abstract

THE importance of determining the abundance of antiparticles in the primary cosmic rays has already been discussed1: for example, Steigman has considered the value of p̄ as a probe in distinguishing various propagation models. We report here on the measurement of p̄/p and H̄e/He in the 4–100 GeV/c range made from a balloon flight in May 1976 of a superconducting magnet spectrometer from Palestine, Texas, under 5,8 g cm−2 of residual atmosphere. The upper limits derived are the most stringent to date.
