Collinear-laser spectroscopy with the bunched-beams technique was used for the study of neutron deficient Rb isotopes, out to Rb74 (N=Z=37) at TRIUMF. The measured hyperfine coupling constants of Rb76,78m were in agreement with literature values. The nuclear spin of Rb75 was confirmed to be I=3/2, and its hyperfine coupling constants were measured for the first time. The mean-square charge radius of Rb74 was determined for the first time. This result has improved the isospin symmetry breaking correction term used to calculate the Ft value, with implications for tests of the unitarity of the Cabibbo-Kobayashi- Maskawa matrix. © 2011 American Physical Society.
