Abstract: Neutrino oscillation studies have demonstrated that neutrinos
have a mass and they mix. Next facilities will need pure, in flavour,
and intense beams for very long-baseline experiments with massive
detectors. The ultimate goal is the discovery and measurement of
CP violation in the lepton sector. The CP-odd terms in the oscillation
probability have different energy dependence with respect to the
CP-even terms. Boosted ions decaying by electron capture with half-lives
of the order of sec. offer the virtue of providing a forward
monochromatic neutrino beam with appropriate properties for a beta-beam
facility. These proton-rich isotopes are of high interest for nuclear
physics studies too.
We have recently performed systematic study of candidate nuclei for the construction of a monocromatic neutrino beam facility in the proton rich rare earth region. In this contribution we show the results of the experimental study of the beta decay of two possible candidate nuclei (152Y b and 150Er) using the Total Absorption Gamma Spectroscopy (TAGS) technique at GSI. A comparison of these results with earlier high resolution measurements will be discussed as well as possible new measurements at Isolde.
