1 Deep inelastic reactions 238 U 248 Cm primary fragments superheavy isotope 208 Pb 278 Sg fission V. Zagrebaev and W. Greiner, 2007

2 New methods: SHIPtrap Isobar separation at A=147 in the purification trap Isomeric state identification in the measurement trap 147 Dy + gs Isomer 147 Er 147 Tb 147 Dy 147 Ho Buncher Extraction RFQ Fusion / transfer products from SHIP Stopping cell Measurement trap Detector Downstream experiments Purification trap M. Block et al MeV 750 keV

3 SHIPtrap: Most recent results, August 2008 M. Block et al. 48 Ca Pb => 254 No + 2n 48 Ca Pb => 252 No + 2n σ = 2 b σ = 900 nb 3 ions/s into gas-cell σ = 400 nb 48 Ca Pb => 253 No + 2n BE = ± 10 keV Excitation frequency / Hz –
