摘要：
A new measurement of the 200Fr α-decay half-life, with improved accuracy compared to previous measurements, has been carried out at the Isolde-CERN on-line mass separator. A half-life of 49(4) ms has been obtained, which is substantially different from earlier literature values. For the 196At daughter decay, a half-life of 389(54) ms and an α branching ratio bα = 94(5)% were measured. In addition, the half-lives of 201, 203, 205Fr and 197,199At are reported.
