Abstract
The spectrum of electrons arising from the decay of the negative mu meson has been determined. The muons are arrested in the gas of a high-pressure hydrogen-filled diffusion cloud chamber. The momenta of the decay electrons are determined from their curvature in a magnetic field of 7750 gauss. The spectrum of 415 electrons has been analyzed according to the theory of Michel. The shape parameter, , is found to be 0.64±0.10. The significance of this result in terms of the beta interaction is discussed.
