Dipole moments and parity violating spin rotations of the neutron

Four different categories of experiments involving slow neutrons are discussed: (1) the most recently completed experiments at the Institut Laue-Langevin (ILL) and at Leningrad which set an upper limit on the electric dipole moment of the neutron, (2) the new experiment now being assembled at the ILL to measure the neutron electric dipole moment with ultra-cold neutrons trapped by total reflection in a neutron bottle, (3) a recent measurement of the neutron magnetic moment at the ILL with an improvement in accuracy by a factor of more than one hundred, (4) the recent observation at the ILL of a parity violating spin rotation when neutrons pass through matter, due, presumably, to the parity violating weak interaction
