Precise half-life measurements for the superallowed beta(+) emitters Ar-34 and Cl-34
(American Physical Society, 2006)
To contribute meaningfully to any test of the unitarity of the Cabibbo-Kobayashi-Maskawa (CKM) matrix, the measured ft value of a superallowed 0(+)-> 0(+) beta(+) transition must be obtained to a precision of 0.1% or better. ...
Branching ratios for the beta decay of Na-21
(American Physical Society, 2006)
We have measured the beta-decay branching ratio for the transition from Na-21 to the first excited state of Ne-21. A recently published test of the standard model, which was based on a measurement of the beta-nu correlation ...
Beta decay of proton-rich nucleus Al-23 and astrophysical consequences
(American Physical Society, 2006)
We present the first study of the beta decay of Al-23 undertaken with pure samples. The study was motivated by nuclear astrophysics questions. Pure samples of Al-23 were obtained from the momentum achromat recoil separator ...

Scattering of Be-7 and B-8 and the astrophysical S-17 factor
(American Physical Society, 2006)
Measurements of Be-7 scattering at 87 MeV on a melamine (C3N6H6) target and of B-8 at 95 MeV on C were performed. For Be-7 the angular range was extended over previous measurements and monitoring of the intensity of the ...
