A series of experiments has been carried out to examine the spatial symmetry properties of
the beta decay of the free neutron. Measurements of angular distributions of the electrons …

using their notation. The terins A and B are 11011-zero only if parity is not conserved and D
is non-zero only if time reversal invariance is violated. The coefficients depend in various …

experiment measuring the correlation of the neutrino momentum and the neutron spin. into …

The β-decay asymmetry of the free neutron is measured by use of a beam of polarized
neutrons and a long solenoidal β spectrometer with 4 π solid angle for electron detection …

The angular correlation between the directions of escape of an electron and neutrino and
neutron spin in the beta decay of polarized neutrons is measured accurately. It is shown that …

The electron neutrino angular correlation coefficient has been measured for the beta decay
of the free neutron by measuring the momentum spectrum of the electrons emitted in a …

The beta-decay asymmetry of the free neutron is measured with polarized neutrons and a
long solenoidal beta-spectrometer with 4π electron-detection solid angle. The asymmetry …

A detailed description of an experimental test of time-reversal invariance in the β decay of
the polarized free neutron is presented. The experiment consists of a measurement of the …

Most of the data has been accumulated using a one-half inch iron block as polarizer and
with an arrangement which records coincidences for one hour with polarized neutrons …

Noninvariance under space reflection and charge conjugation has now been established for
beta decay processes. Invariance under time reversal remains an open question, however …
