Can someone translate these bubble chamber tracks?

    I was looking for more details about this picture:


    I think I see a few places where electron/positron pairs arise but can't be sure. Does anyone know what types of particles (energies) are in this image.

    The strength of the magnetic field used and a sense of scale would be needed to calculate energies. Field direction will tell you charge of the particles.

    Positron electron pair in top left?

    It's a very old picture. Nobody uses bubble chambers any more, especially not Fermilab.
