Neutron lifetime measurements with a large gravitational trap for ultracold neutrons

RADIOACTIVITY 1n(β-); measured Iβ, T1/2 of free neutron, storage cycles for two different holding times, temperature dependence of the UCN storage time, inverse UCN loss rate, neutron count rates before (reactor cycle 179) and after (reactor cycle 181) using gravitationally trapped ultra-cold neutrons (UCN) at Institute Laue-Langevin (ILL) using the PF2 MAM UCN beam; deduced trap-neutron collision frequency, systematic error in T1/2 measurements using Monte Carlo simulations, influence of the residual gas on UCN storage. Comparison with previous experimental values in the last 17 years, and with evaluations by Particle Data Group. Discussed problem of a 3.9σ discrepancy between measurements of half-life of free neutron using neutrons in beams and those with stored ultracold neutrons (UCN).

New search for the neutron electric dipole moment with ultracold neutrons at ILL

NUCLEAR MOMENTS 1n; measured Ramsey resonance curves, neutron electric dipole moment (EDM) using ultracold neutrons (UCN) from High-Flux Reactor of ILL-Grenoble and double-chamber magnetic resonance spectrometer developed at PNPI-Gatchina; deduced an upper limit of EDM. Discussed possibilities for further improvement.
