Caption: Bubble chamber photograph of the production & decay of a lambda particle. One of the negative kaons entering from below collides with a proton in the liquid hydrogen filling the chamber, & produces a positive & negative pion & the lambda, which is neutral & therefore invisible. The lambda is rev- ealed when it decays into a proton & a muon, which form the well- defined V-shaped pair of tracks at upper centre. The muon soon decays into an electron (the large spiral) & an invisible neutrino. Note how the positive pion knocks out an atomic electron, which forms the tighter of the two electron spirals. The scale up the side is in units of about 9cm. Photo taken at 72-inch (180cm) bubble chamber at
