The pBARp annihilation cross-sections at 66.4-68.9-71.4 MeV/c have been measured using the presently instrumented part of the OBELIX spectrometer. The results have been obtained at pBAR energies (almost-equal-to 2.5 MeV) by one order of magnitude smaller than in any existing experiment concerning the in-flight antiproton-proton annihilation. The branching ratios for the annihilations in two, four and six charged mesons turn out to be quite similar to those for annihilation at rest in liquid hydrogen.
