Beta-decay of the very neutron-deficient Kr isotope, 70Kr, was studied at RIKEN-RIBF using the EURICA cluster array. The experiment significantly increased our knowledge of the beta-decay of this isotope. Namely, 16 new γ-ray transitions were identified and the half-life was derived from time correlations of the beta particles (t iβ 1/2 = (44.99 ± 0.16) ms) and from the decay curves of the observed γ-ray transitions (t iβγ 1/2 = (45.16±0.71) ms), respectively.
