Abstract:
The pbar He-4 anmhllatlon cross section averaged over the interval 40-50 MeV/c has been measured using a streamer chamber in a magnetic field The measured value is 1342 +- 250 mb . It agrees with a behavmur like 1/p of the annihilation cross section. Our result has been obtained at the lowest momentum achieved till now in measurements of antlproton anmhllatlon in flight.
