General Comments:

2009St16,2008StZY thesis: 195Re nuclide identified in the reaction 9Be(208Pb,X) with a beam energy of 1 GeV/nucleon produced by the SIS-18 accelerator at GSI facility. Target thickness=2.5 g/cm2. Fragments identified in flight by the Fragment Separator (FRS) operated in achromatic mode based on time of flight, Bρ and energy loss. Data collected on six FRS magnetic rigidity settings centered on: 206Hg, 203Ir, 202Os, 199Os, 192W, and 185Lu. Nuclides halted in a passive stopper surrounded by the RISING array in "Stopped Beam " configuration.

Experimental identification in a similar experiment at GSI in 2008St20 and 2009Al30.

2009Ku28: 195Re was produced by the in-flight fragmentation of relativistic heavy projectiles. The Beam was 208Pb at 1 GeV/α bombarding a 9Be target. Fragment Recoil Separator (FRS) was used to identify 195Re residues. The 195Re nuclei were implanted into an array of four double-sided silicon strip detectors with a surface of 25 cm2, 1 mm thickness each. Measured half-life from position-time correlations between the implanted fragments and the subsequent β decay.

2008KuZY, 2007KuZW, 2007KuZZ and 2005KuZU superseded by 2009Ku28
