We have measured the half-life of the electron-capture (ec) decay of 97Ru in a metallic environment, both at low temperature (19 K), and also at room temperature. We find the half-lives at both temperatures to be the same within 0.1%. This demonstrates that a recent claim that the ec decay half-life for 7Be changes by 0.9% ± 0.2% under similar circumstances certainly cannot be generalized to ot...

During the Surface Heat Budget of the Arctic Ocean (SHEBA) project in October 1997 the first measurements of 7Be ever made within the Arctic Ocean were used to reconstruct he evolution of the mixed layer over the previous season and confirmed that the reservoir of heat beneath the fall mixed layer was emplaced in the summer, rather than input cumulatively over several seasons or advected in fro...

A novel scheme for measuring the cross section of the 7Be(p,γ)8B reaction, the major source of high energy neutrinos from the sun, is presented. The scheme involves a strictly uniform particle beam and overcomes some of the recognized experimental uncertainties of previous measurements. A new measurement of σ[7Li(d,p)8Li] has been carried out using this setup, and the present value of σ[7Li(d,p...
