AB  - The decay of O-19(beta(-)) and Ne-19(beta(+)) implanted in niobium in its superconducting and metallic phases was measured using purified radioactive beams produced by the SPIRAL GANIL facility. Half-lives and branching ratios measured in the two phases are consistent within a 1 sigma error bar. This measurement casts strong doubts on the predicted strong electron screening in a superconductor, the so-called superscreening. The measured difference in screening potential energy is 110(90) eV for Ne-19 and 400(320) eV for O-19. Precise determinations of the half-lives were obtained for O-19, 26.476(9) s, and for Ne-19, 17.254(5) s.

AB  - The unbound nucleus Na-18, the intermediate nucleus in the two-proton radioactivity of Mg-19, was studied by the measurement of the resonant elastic scattering reaction H(Ne-17,p)Ne-17 performed at 4 A.MeV using a radioactive beam from the SPIRAL Facility. Spectroscopic properties of the low-lying states were obtained in an R-matrix analysis of the excitation function. (C) 2012 Elsevier B.V. All rights reserved.
