High precision measurements of the ft values for superallowed Fermi β decays are crucial for providing stringent tests of electroweak theory and constraining possible new physics beyond the Standard Model. To achieve this goal, ft values for these decays must be determined experimentally to ± 0.10% or better. In this work, a high-precision half-life measurement, one of the key ingredients for...
As one moves away from stable isotopes and deeper into the neutron-rich region, the likelihood of β-delayed neutron (βn) emission decay increases. The ability to understand the neutron emission probabilities and the neutron energy spectrum can reveal details of the nuclear structure that a conventional β-decay study using only γ-ray detection cannot. We propose to build the Detector Array for...
One of the challenges faced while studying the nuclear many-body problem is the nature of the nucleon-nucleon interaction. In recent decades, models for the nucleon-nucleon interaction were produced from a power counting expansion in Chiral Effective Field theory (EFT). As a result, these modern nuclear interactions have an advantage over previously used phenomenological potentials, since they...
Nuclear theories often operate under the assumption that the strong nuclear force is charge independent. As a result, it is expected that mirror nuclei, which are identical under the exchange of total number of protons and neutrons, will have similar nuclear structures when Coulombic contributions are considered. Under the assumption of charge independence, protons and neutrons are grouped...
An understanding of the properties and behaviour of neutron-rich nuclei is essential in the study of phenomena such as neutron stars and supernovae. Successive addition of neutrons to an atomic nucleus yields isotopes that may or may not be stable: past a certain point, a nucleus experiences a decay process in which it leaks out neutrons, known as a neutron drip line. For nearly 20 years, the...
Heavy-ion storage rings connected to radioactive beam facilities offer a unique environment for nuclear physics experiments. So far, storage rings have been only coupled to in-flight fragmentation facilities, for example the ESR and the CRYRING at GSI Darmstadt, Germany, the CSRe at HIRF in Lanzhou, China, and the Rare RI Ring at RIKEN Nishina Center in Japan.
