✦ Synopsis

The annihilation fractions of the pp annihilation at rest into ππ, πη, ηη, φπ 0 , K K and η(1440)ππ at different target densities are reviewed in order to determine their branching ratios from S and P antiprotonic atom sublevels and the sublevel population fractions. Particular emphasis is given to the incompatibility of some annihilation fraction measurements and to the expected dependence of the pp atom sublevel population fractions on the target density. The population fraction of the 3 P 0 sublevel in liquid target turns out to be higher than its statistical weight.

Measurements of two-body branching ratios for pp annihilations at rest in liquid and gaseous (12ρ STP ) hydrogen are reported. Channels studied are pp → π 0 π 0 , π 0 η, K 0 S K 0 L , K + K -. The branching ratio for the π 0 π 0 channel in liquid H 2 is measured to be (6.14 ± 0.40) × 10 -4 . The res
