Direct mass measurements on the superallowed emitter74Rb and its daughter74Kr: Isospin-symmetry-breaking correction for standard-model tests [link]Website  abstract   bibtex   
The decay energy of the superallowed emitter 74Rb and its daughter 74Kr were determined using direct Penning trap mass measurement. Time-of-flight resonance technique was used for the calculation of decay and was found to be Q=10416.8keV. It was found that two most precise 74Rb lifetime measurements yielded a mean-half life of T 1/2=64.776ms. The branching ratio of the analog transition was found to be 99.5%.
