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 (tiβ 1=2 = (44:99±0:16) ms) and from the decay curves of the observed γ-ray transitions (tiβ 1=2 = (45:16±0:71) ms), respectively.

Abstract
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 (tiβ 1=2 = (44:99±0:16) ms) and from the decay curves of the observed γ-ray transitions (tiβ 1=2 = (45:16±0:71) ms), respectively.
