Abstract: A complete survey is presented of all half-life and branching-ratio measurements related to the isospin T=1/2 mirror beta transitions ranging from He-3 to Mo-83. No measurements are ignored, although some are rejected for cause. Using the decay energies obtained in the 2003 Mass Evaluation experimental ft values are then determined for the transitions up to V-45. For the first time also all associated theoretical corrections needed to convert these results into "corrected" Ft values, similar to the superallowed 0(+)-> 0(+) pure Fermi beta transitions, were calculated. Precisions of the resulting values are in most cases between 0.1 and 0.4%. These Ft(mirror) values can now be used to extract precise weak interaction information from past and ongoing correlation measurements in the beta decay of the T=1/2 mirror beta transitions.
