$\alpha$-decay of neutron-deficient $^{200}$Fr and heavier neighbours
A new measurement of the $^{200}$Fr $\alpha$-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...

| description | A new measurement of the $^{200}$Fr $\alpha$-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 $^{196}$At daughter decay, a half-life of 389(54) ms and an $\alpha$- branching ratio $\alpha$=94(5)% were measured. In addition, the half-lives of $^{201,203,205}$Fr and $^{197,199}$At are reported. |
