CERN-ARCH-BUBBLE-CHAMBER-PHOTO-13134
Interactions of the particles : Antiprotons (momentum: $\pm$ 600 MeV/c) speeding through the liquid hadrogen of the 81 cm bubble charmber (set up at CERN by the Saclay C.E.N. and the Ecole Polytechnique of Paris). Viewing the photograph horizontally, one can see several antiprotons entering the chamber on the left and annihilating themselves with protons of the liquid hydrogen. This annihilation on the left of the picture produces a number of pions. Beneath the annihilation there are tracks of a collision between another antiproton and a proton. The latter undergoes an elastic scattering and leaves a short track towards the top of the chamber, while the antiproton continues its run. Another elastic scattering is visible towards the right. In the centre of the photo there is yet ancther annihilation.

CERN-ARCH-BUBBLE-CHAMBER-PHOTO-13130
Interactions of the particles : A slow antiproton comes to rest in a hydrogen bubble chamber and annihilates with a proton. In the annihilation a neutral $K^{0}$ meson, a $K^{-}$ meson and a $\pi^{+}$ meson are created. The $K^{0}$ decays into $\pi^{+}$ and $\pi^{-}$. The $K^{-}$ interacts with a second proton hitting a $\Sigma^{+}$ and a $\pi^{-}$. The $\Sigma^{+}$ decays into a proton and a $\pi^{0}$
