Abstract:
We have measured a value of 15.5 +- 2.9 mb for the pbar He-4 break-up cross section at 179.6 MeV. This low value is in agreement with the prediction of the Glauber model and is due to the large probability for the antiproton to annihilate into the nuclei, which makes only a surface layer of the nuclear volume effective for the break-up process.
