RT Journal Article T1 The experiments to determine the electron capture and beta-decay of B-8 into the highly excited states of Be-8 A1 Benito García, Jaime A1 Fraile Prieto, Luis Mario A1 otros, ... AB The main goal of this work is to study the structure of the highest energy states in Be-8 populated following the beta(+)-decay and the electron capture (EC) of B-8. With this aim, two experiments were performed at ISOLDE-CERN in 2017 and 2018. The first experiment had the aim to resolve the 2(+) doublet at 16.6 and 16.9 MeV, in order to study their isospin mixing. The second experiment aimed to determine a value or give an experimental upper limit to the branching ratio of the exotic EC-p decay. In this paper, we present the experimental setups and we discuss the analysis and present the preliminary results obtained so far.
