  1. 1. High-precision beta-decay studies to test the weak-interaction standard model
    Bertram Blank (CEN Bordeaux-Gradignan)

    Invited
    Nuclear beta decay transforms up quarks in down quarks and vice versa. Therefore, high-precision measurements of beta decay allows under certain conditions to test the standard model of weak interaction. In particular, the conserved vector current (CVC) hypothesis can be tested and the Vud element of the CKM quark mixing matrix can be determined. For this purpose, high-precision data for 0+ -...

  2. 42. $\beta$-delayed neutron spectroscopy at the ISOLDE Decay Station
    Miguel Madurga Flores (CERN)

    Invited
    The investigation of isotopes far from stability provides a substantial test of our understanding of the forces involved in organizing nuclear matter. Ground state properties, such as its mass or spin parity, and beta-decay properties, like the half-life or the neutron branching ratio are the typical observables that must be correctly reproduced to trust a nuclear theory calculation. In...

  3. 12. Beta-delayed neutron spectroscopy in 51-54K

    In neutron-rich nuclei, especially near shell-closures, the increasing Q-value of beta decays and the lowering of the neutron-separation threshold, lead to the dominance of beta-delayed neutron emission as decay mode. At the same time, Q-values well above 10 MeV provide the possibility to study highly-excited particle-hole states populated by the GT decay. A measurement was...

  4. 20. Recent results from the neutrino mass experiment ECHo using the new detectors with Ho-163 implanted at ISOLDE
    Dr Loredana (for the ECHo Collaboration) Gastaldo (Kirchhoff-Institute for Physics, Heidelberg University)
    02/12/2015, 18:00
    Submitted
    The Electron Capture in Ho-163 experiment, ECHo is designed to investigate the electron neutrino mass in the sub-eV region using high-precision measurements of the Ho-163 electron capture spectrum. The very good results obtained from the first prototypes of metallic magnetic calorimeters with ion-implanted Ho-163, among which the calorimetric measurement of the Ho-163 spectrum with the best...
