Meson Experiments with Enrico Fermi

I THOUGHT you might like to hear more about what it was like to work with Enrico Fermi, in another setting. Let me tell you about the time we decided to work together with the pi mesons. It was just about four years ago. At Chicago, we had just completed a large synchrocyclotron which could accelerate protons to 450 Mev. Fairly intense meson beams, rather well defined in energy, could be obtained from this machine.
