Reaching the drip lines

Best way to reach drip lines: • fragmentation or in-flight fission • e.g. 48Ni, 100Sn, 78Ni etc

fragment separator fragmentation of radioactive beams

EURISOL Instrumentation

Beta-decay studies

• super-allowed 0+ 0+ decays: CVC, CKM matrix• b-delayed decays: , p, 2p, 3p, n, 2n, 3n
