Precise Half-Life Measurement of Ga

In last year’s Progress Report we reported on measurements of the β-decay of Ga, including a preliminary value for its halflife [1]. We report here on an additional measurement of the half-life focused on exposing systematic effects that could affect the result. We obtained Ga from the MARS recoil spectrometer by bombarding a cooled hydrogen gas target with Zn at 42A MeV. Special care was taken...

Precise Half - Life Measurement of 22 Mg

As part of our program [1] to test CKM unitarity via superallowed ∃-decays, we reported in last year’s Progress Report [2] that we were well advanced in making a measurement of the half-life of Mg. At that time we had obtained a preliminary result but had not yet fully explored all possible systematic errors. Subsequently, an additional experiment was performed at the MARS spectrometer with our...

Measurement of the Half - Life of 22 Mg

Measurement of the beta decay half-life of 17B.

The properties of nuclei far from stability provide a stringent test of the validity of shell model Hamiltonians derived from data for nuclei near the valley of stability. Failure of shell model calculations to extrapolate to nuclei far from stability may indicate a breakdown of symmetries assumed in the model. Such a breakdown may provide evidence for new regions of deformation as were found f...
