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. 1742-6588 10.1088/1742-6596/1643/1/012130 https://hdl.handle.net/20.500.14352/8536 https://doi.org/10.1088/1742-6596/1643/1/012130 https://iopscience.iop.org/ The experiments to determine the electron capture and beta-decay of B-8 into the highly excited states of Be-8
