First experimental determination of the charge radius of ${}^{74}$Rb and its application in tests of the unitarity of the CKM matrix

E. Mané, A. Voss, J. A. Behr +9

Collinear-laser spectroscopy with bunched-beams technique was used for the study of neutron deficient Rb isotopes, out to ${}^{74}$Rb ($N=Z=37$) at TRIUMF. The measured hyperfine cou…
