The discovery that the neutrinos from pion-muon-neutrino (7r-J..!-v) decay are distinct from
the neutrinos of/3 decay has made it clear that a distinct class of particles exists which, so …

We investigate the effects, on free muon production and decay, of a non-zero mass for the
muon's neutrino. The quantity most sensitive to the mass of the muon's neutrino is the shape …

Recently, some other aspects of this problem have been discussed by several authors.~ 6
The purposes of this note are to derive the spectrum of the photon emitted in the decay of …

The muon is known to us for a little more than forty years. It was discovered by Anderson and
Neddermeyer [1] around 1936 in studies of cosmic rays with cloud chambers and Geiger …

Some processes due to free neutrinos which heretofore had not been considered are
discussed. Especial attention is given to those processes which in principle may help to …

In 1935 Yukawa (1) postulated the existence of a mediator of strong interactions. It was
called mesotron because, from the range of nuclear forces, its mass was estimated to be'" …

The apparent absence of muon-electron transi-tions without neutrinos, such as p. e+ y, p. 3e,
and p+ p~ e+ p, leads one to suspect that there is a new conservation law forbiddingthem …

Date of birth of the muon method is unknown, as are the names of its parents. What's more,
there are strong grounds to believe that this issue will never be elucidated in the future …

The name muonic atom is used to designate a system which consists essentially of a single
negative muon μ− bound to a single atomic nucleus. The term atom implies a similarity with …

(2) The spectrum of positrons emitted in the decay of u-mesons does not contradict the
conjecture that the two neutral particles produced during this decay are identical and obey …
