Two-proton radioactivity was observed in 2002 in the decay of Fe-45. However, the experiments performed at that time did not allow the observation of the two protons directly. [...]

Simultaneous measurements of the $\beta$ -neutrino angular correlation in $^{32}$Ar pure Fermi and pure Gamow-Teller transitions using $\beta$ -proton coincidences
/ Araujo-Escalona, V. (Leuven U.) ; Atanasov, D. (Leuven U. ; CERN) ; Fléchard, X. (ENSICAEN) ; Alfaurt, P. (CENBG, Gradignan) ; Ascher, P. (CENBG, Gradignan) ; Blank, B.

We report first time measurements of the beta-neutrino angular correlation based on the kinetic energy shift of protons emitted in parallel or anti-parallel directions with respect to the positron in the beta decay of $^{32}$Ar. This proof of principle experiment provided simultaneous measurements for the superallowed 0$^+$~$\rightarrow$~0$^+$ transition followed by a 3356~keV proton emission and for a Gamow-Teller transition followed by a 2123~keV proton emission.

The beta-decay half-life of 26Si was measured with a relative precision of 1.4*10e3. The measurement yields a value of 2.2283(27) s which is in good agreement with previous measurements but has a precision that is better by a factor of 4. [...]

The $\gamma$ -decay branching ratios of $^{49}$V have been studied in the $\beta$ /EC decay of $^{49}$Cr. The $\gamma$-ray spectrum has been measured with a 70% relative efficiency co-axial germanium detector calibrated in efficiency with a precision of about 0.5%. [...]

Beta - neutrino correlation measurements are key in the research of physics beyond the Standard Model. In pure Fermi beta transitions, the beta-neutrino correlation coefficient, a βν, is sensitive to the presence of scalar currents. [...]

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.
