Abstract

The frequency of the protonium annihilation channel p̄p → K_SK_L has been measured at three different target densities: liquid hydrogen (LH), gaseous hydrogen at NTP conditions and gaseous hydrogen at low pressure (5 mbar). The obtained results are: f (p̄p → K_SK_L,LH) = (7.8 ± 0.7_stat ± 0.3_sys) × 10^-4, f(p̄p → K_SK_L, NTP) = (3.5 ± 0.5_stat ± 0.2_sys) × 10^-4 and f(p̄p → K_SK_L, 5 mbar) = (1.0 ± 0.3_stat ± 0.1_sys) × 10^-4. Since the K_SK_L final state can be originated only from the ³S₁ initial state, these values give direct information on the scaling of the protonium spin-triplet S-wave annihilation probability with the density.
