High-precision half-life determination of $^{14}$O via direct $\beta $ counting / Sharma, S. (Regina U.) ; Grinyer, G.F. (Regina U.) ; Ball, G.C. (TRIUMF) ; Leslie, J.R. (Queen's U., Kingston) ; Svensson, C.E. (Guelph U.) ; Ali, F.A. (Guelph U. ; Sulaimaniya U.) ; Andreoiu, C. (Simon Fraser U., Dept. Chem.) ; Bernier, N. (TRIUMF ; British Columbia U. ; Western Cape U. ; Zululand U.) ; Bhattacharjee, S.S. (TRIUMF) ; Bildstein, V. (Guelph U.) et al.
The half-life of the superallowed Fermi $\beta^+$ emitter $^{14}$O was determined to high precision via a direct $\beta$ counting experiment performed at the Isotope Separator and Accelerator (ISAC) facility at TRIUMF. The result, $T_{1/2}$($^{14}$O) = 70619.2(76) ms, is consistent with, but is more precise than, the world average obtained from 11 previous measurements. [...]

(Guelph U.) et al.
In an experiment performed at the ISOLDE facility of CERN, the super-allowed beta-decay branching ratio of 10C was determined with a high-precision single-crystal germanium detector. In order to evaluate the contribution of the pile-up of two 511 keV gamma quanta to one of the gamma-ray peaks of interest at 1021.7 keV, data were not only taken with 10C, but also with a 19Ne beam.

Antiproton cloud compression in the ALPHA apparatus at CERN / Gutierrez, A (British Columbia U.) ; Ashkezari, M D (Simon Fraser U.) ; Baquero-Ruiz, M (UC, Berkeley) ; Bertsche, W (Manchester U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Burrows, C (Swansea U.) ; Butler, E (Imperial Coll., London ; CERN) ; Capra, A (York U., Toronto, Dept. Phys. Astron.) ; Cesar, C L (Rio de Janeiro Federal U.) ; Charlton, M (Swansea U.) ; Dunlop, R (Simon Fraser U.) et al.
We have observed a new mechanism for compression of a non-neutral plasma, where antiprotons embedded in an electron plasma are compressed by a rotating wall drive at a frequency close to the sum of the axial bounce and rotation frequencies. The radius of the antiproton cloud is reduced by up to a factor of 20 and the smallest radius measured is ∼ 0.2 mm. [...]
