对从{sup 3}He到{sup 83}Mo的所有同位旋T=1/2镜面{beta}跃迁的半衰期和分支比测量进行了全面的综述。没有任何测量结果被忽略，尽管有些测量数据因某些原因而被拒绝。使用在2003年质量评估中获得的衰变能量，然后确定了直到{sup 45}V的跃迁的实验ft值，并且第一次计算了将这些结果转换为‘’校正‘’ft值所需的所有相关的理论修正，类似于超允许的0{sup+}{产额}0{sup+}纯费米{beta}跃迁。在大多数情况下，结果值的精度在0.1%到0.4%之间。这些Ft{sup Mirror}值现在可以用来从T=1/2镜像{beta}跃迁的β衰变中过去和正在进行的关联测量中提取精确的弱相互作用信息。
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 {sup 3}He to {sup 83}Mo. 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 {sup 45}V. For the first time also all associated theoretical corrections needed to convert these results into ''corrected''Ft values, similar to the superallowed 0{sup +}{yields}0{sup +} pure Fermi {beta} transitions, were calculated. Precisions of the resulting values are in most cases between 0.1 and 0.4%. These Ft{sup 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.
