Solid State Physics • lattice location of impurities in semi-conductors by channeling • new developments • fast read-out • lower noise level • shorter T1/2 • lower electron energies • - new probes (65Ni, 61Co, 27Mg, 8Li,) • lattice location in semiconductors • related to ferromagnetism NuPECC 22-23 June 2007
REX post-accelerator • Originally constructed by several CERN member states ~ 15 MCHF • Utilises now 50% ISOLDE running time • REX has accelerated 43 different RIB • Present RIB yield from ISOLDE allows 10% of all 700 radioisotopes be used NuPECC 22-23 June 2007
