The p annihilation at rest in a NTP 4 He-gas target has been studied by means of the Obelix spectrometer installed at the LEAR accelerator of CERN. Reactions with production of 2Ο -2Ο + , 2Ο -3Ο + , 2Ο -2Ο + p, 2Ο -Ο + 2p, 2Ο -3p (with p Ο > 80 MeV/c and p p > 300 MeV/c) have been selected and singl
The dependence of the strangeness production on the number of nucleons involved in the annihilation process is investigated experimentally in pp and p4 He annihilation at rest. In He, annihilations with the involvement of one and several nucleons (B = 0 and B 1 baryonic number, respectively) are ide
