Ultracold neutrons (UCN) have been established as a valuable tool in precision fundamental neutron physics reseach since many years.
In order to perform precision measurements with UCN, strong and reliable UCN sources are needed, and such sources are being operated at several universities and research centers world-wide. The density of UCN provided to experiments at a UCN source is an...

The mean lifetime for $\beta$-decay of a free neutron is an interesting empirical target because it is an input for calculation of light element abundances in the early universe, affects predictions from cosmic microwave background data about the number of effective neutrino species, and in combination with other $\beta$-decay observables can provide sensitive tests for physical phenomena not...
