现在大家都知道，在弱费米相互作用中，宇称不守恒，这通常会导致发射粒子的自旋纵向极化。在π衰变1中发射的μ子和在β衰变2中发射的电子的非常强的极化已经被探测到。本文报道的实验旨在探测非极化μ子衰变中发射的正电子的纵向极化。
IT is now well known that parity is not conserved in weak Fermi interactions, and that this generally results in longitudinal polarization of the spins of the emitted particles. Very strong polarizations of the muons emitted in pion decay1, and of the electrons emitted in beta decay2, have already been detected. The experiment reported here was aimed at detecting longitudinal polarization of the positrons emitted in the decay of unpolarized muons.
