T_z= -1 → 0β decays of ⁵⁴Ni, ⁵⁰Fe, ⁴⁶Cr, and ⁴²Ti and comparison with mirror (³He, t) measurements

RADIOACTIVITY ⁴²Ti, ⁴⁶Cr, ⁵⁰Fe, ⁵⁴Ni(β⁺), (EC)[from Be(⁵⁸Ni, X), E=680 MeV/nucleon]; measured Eγ, Iγ, γγ-, βγ-coin, implant-β correlations, half-lives from β and γ decay curves, yields of reaction products using fragment separator FRS, particle detectors and RISING Ge array at SIS-18 synchrotron facility of GSI. ⁴²Sc, ⁴⁶V, ⁵⁰Mn, ⁵⁴Co; deduced levels, J, π, β feedings, logft, B(GT+). Comparison of B(GT) values with those from (³He, t) reactions at RCNP-Osaka. Superallowed Fermi transitions between T_z=-1 and T_z=0 nuclei for testing the unitarity of the CKM matrix.
