10C superallowed branching ratio and the Cabibbo-Kobayashi-Maskawa matrix unitarity. Academic Article uri icon


  • A measurement of the superallowed 0+0+ branching ratio in 10C performed with the 8 gamma-ray spectrometer is described. From the measured branching ratio, we extract a new precise value of Ft(10C)=3076.7(6.0) s. This does not support previously suggested Z- or Z2-dependent corrections to the superallowed 0+0+ data set, which removed the apparent nonunitarity of the Cabibbo-Kobayashi-Maskawa matrix. 1995 The American Physical Society.
