- Abstract
A new measurement of the200Fr a-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 the196At daughter decay, a half-life of 389(54) ms and an a branching ratioba = 94(5)% were measured. In addition, the half-lives of201, 203, 205Fr and197,199At are reported.
