  1. Interaction of a beam (K-) with a proton producing one negative and one positive particle.

  2. Amongst the tracks in this region a photon has converted into an electron-position pair. The electron leaves the chamber but the complete spiral path of the positron is detected and marked as k.

  3. There are two positive and one negative track produced in this interaction. This cannot be from decay of neutral particles because of charge conservation and is likely to be due to the interaction of a neutron with a proton.
