pbarp, pbarD, pbar sup 4 He annihilation cross sections at low energy
New measurements of the pbarp annihilation cross section have been performed with the OBELIX apparatus between 37 and 70 MeV/c. From previous samples of data it was already clear that the 1/p behaviour for the annihilation cross section is drastically modified at very low momenta, due to the Coulomb...

| description | New measurements of the pbarp annihilation cross section have been performed with the OBELIX apparatus between 37 and 70 MeV/c. From previous samples of data it was already clear that the 1/p behaviour for the annihilation cross section is drastically modified at very low momenta, due to the Coulomb interaction. However, at the lowest measured momentum (43.6 MeV/c), the annihilation cross section was unexpectedly high; this evidence suggested a more accurate investigation of this region. Furthermore, measurements of annihilation cross section have been performed with pbar impinging on D sub 2 and sup 4 He targets. |
