An experiment of high physical interest.


An experiment is reported, which firstly proves the existence of neutral weak interactions. The experiment is carried out with a 200-GeV muon beam scattered at a carbon target by means of asymmetry measurements. The schematic construction of the experimental plant NA4 in the European Nuclear Science Center (CERN) is described. Klein,-M.; Nowak,-W.D.; Riemann,-T.
