Accurate measurement of the lifetime of the neutron (which is unstable to beta decay) is
important for understanding the weak nuclear force and the creation of matter during the Big …

The precise value of the mean neutron lifetime, τn, plays an important role in nuclear and
particle physics and cosmology. It is used to predict the ratio of protons to helium atoms in …

We propose an experimental technique to measure the neutron β-decay lifetime using
ultracold neutrons (UCN) produced and stored in a superfluid-4 He-filled magnetic trap …

We report a measurement of the neutron lifetime using ultracold neutrons stored in a
magneto-gravitational trap made of permanent magnets. Neutrons surviving in the trap after …

We present a conceptual design for an experiment to measure the neutron lifetime with a
relative accuracy of 10− 4. The measurement will be performed by observing the decay rate …

Our experiment using gravitationally trapped ultracold neutrons (UCN) to measure the
neutron lifetime is reviewed. Ultracold neutrons were trapped in a material bottle covered …

We present measurements of the neutron lifetime (7,) carried out with a gravitational trap for
ultracold neutrons. We show that statistical uncertainty in the measured storage time is the …

Current values of the neutron β-decay lifetime have come under scrutiny due to a large
disagreement between recent precise measurements using trapping of ultra-cold neutrons …

Neutron lifetime is one of the most important physical constants: it determines parameters of
the weak interaction and predictions of primordial nucleosynthesis theory. There remains the …

We present the status of an experimental setup designed and built for the measurement of
the neutron lifetime and we describe also details about the measuring sequence. The …
