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
