Future for (Stopped) RISING.....the road to DESPEC.

D. Rudolph et al., RISING, Feb/Mar'06

Stopped Rising GSI: 15 x 7 element CLUSTERs Photopeak efficiency ~11% at 1.3 MeV....best array in the world for such studies....bar none.

Future: European Radioactive Ion Beam (fragmentation) facility: FAIR (Facility for Antiproton and Ion Research) (Darmstadt, Germany) low-energy cave MeV/u fragmentation/fission ~1GeV/u fragment separator 350m ring branch

Open questions in nuclear physics limit of existence, neutron skins, change in the shell structure, weak binding effects, nucleosynthesis …

Far future: FAIR yields

Future β decay: RISING active stopper (2007) (J.Benlliure, P. Regan et al.) isomeric decay: CERN-ISOLDE

Advanced GAmma Tracking Array High photo-peak efficiency Good angular resolution <1degree FWHM=10 keV at β=50% = 5 keV at β=20% Ideal for high velocity beams
