    Notes: Abstract Laser trapping and cooling techniques are now being applied to the study of nuclear β-decay at several labs. A magneto-optical trap (MOT) provides a localized source of atoms suspended in space, so the low-energy recoiling nuclei can freely escape and be detected in coincidence with the β. This allows reconstruction of the neutrino momentum, and the deduction of the β-v correlation in a more direct fashion than previously possible. In addition, the nuclei can be polarized by atomic techniques, opening a new class of spin correlation measurements to test the degree to which parity is maximally violated in the weak interaction. Our present experiment has detected several hundred thousand recoil-β+ coincidences from the 0+ → 0+ pure Fermi decay of 38mK, produced at the on-line isotope separators TISOL and ISAC at TRIUMF. Our goal is to set constraints on non-Standard Model scalar bosons competitive with high-energy colliders and more conventional β-v correlation experiments.

    Radioactive Beams: A Probe for Atoms and Nuclei (2000)
    Springer
    Journal of radioanalytical and nuclear chemistry 243 (2000), S. 59-67

    Notes: Abstract A brief summary of the new technical developments of producing intense, energetic radioactive heavy ion beams is provided with some insight of what is happening in the area of nuclear science. These developments have revitalized the entire field of nuclear chemistry and physics, and have provided useful probes for such areas as nuclear astrophysics and condensed matter physics. These are also applications of these new beams in the areas of nuclear medicine and radiopharmacology that have not been mentioned. In many ways, with the start of the next millennium, it is clear that the study of the nucleus is still as important area of research as it was at the start of this century. There are important questions that need to be answered and these new probes represents a first step towards finally addressing these questions in a meaningful fashion.
