Ultracold neutrons are neutrons that exhibit the peculiar behavior of being able to be stored in material bottles for periods ranging up to their beta-decay lifetime (~15 min). They present an attractive avenue for performing fundamental neutron experiments such as: searching for a non-zero neutron electric dipole moment (nEDM), precise measurement of the neutron lifetime, and precision...
The TUCAN collaboration aims to provide an ultra-precise measurement of the neutron electric dipole moment, resulting in a planned sensitivity of 10-27 e*cm. EDM experiments of this kind require measuring changes in the precession frequency of ultracold neutrons as they are subjected to parallel and anti-parallel electric and magnetic fields. In order to reach the planned sensitivity, precise...
Bound-state beta-decay ($\beta_b^-$-decay) is an exotic $\beta^-$-decay mode where the electron is emitted directly into a bound orbital of the daughter nuclei. The electron is emitted into the K- or L-orbitals so this decay mode is only possible for highly charged ions. The first experimental confirmation of $\beta_b^-$-decay was achieved 30 years ago at the Experimental Storage Ring (ESR) at...
