Abstract: | An improvement of the ion source of the online fission product separator OSTIS allowed us to identify the new isotopes100Rb(50±10 msec),100Sr (170±80 msec) and148Cs(130±40 msec). Half-lives for99Rb(59±4 msec),99Sr(290±40 msec) and147Cs(235±10 msec) were redetermined. All values were obtained by following the activity build-up and decay with β-multiscaling and γ-multispectra measurements. |
