Beta-decay half-lives of Kr-70 and Rb-74

摘要

Beta-decay half-lives of two nuclei close to N = Z line, Kr-70 and Rb-74, have been measured at the ISOLDE mass-separator facility at CERN. Importance of these half-lives on two ingredients explaining existence and development of the Universe, the astrophysical nucleosynthesis and the Standard Model, are discussed.
