Abstract

The p̄p total annihilation cross section has been measured, with the OBELIX apparatus at LEAR, at ten values of the antiproton incident momentum between 43 and 175 MeV/c. The values of the cross section show that the well-known 1/p behavior of the annihilation cross section is drastically modified at very low momenta, which demonstrates the important role of Coulomb forces in low-energy p̄p interaction. Moreover, they do not present any explicit resonant behavior. Around 50 MeV/c, a preliminary value of the cross section for the K_SK_L channel is obtained too. * This article was submitted by the authors in English.
