ISOL PropertiesIn ISOL you have a driver beam, often protons that strikes a target say ofuranium carbide heated to very high temperatures and then the radio active productis released and accelerated to energy of experiment.Advantage- can get beams of low energy that are intense.Disadvantages- target chemistry and beam production very difficulteach beam must be separately developednot possible to study short lived isotopessources are very radioactive so really need severalsource boxes (typical cost $1.5M)In flight beam productionFragment incoming beam on a Be target to produce product of interestfor example use a 48 Ca primary beam to produce 44 SAdvantages- Study very short lived nuclei, can use very thick targetsDisadvantages-beams are moving at 0.5c so gamma rays have huge Dopplercorrections, and theory of transfer reactions not well developedAt present the fragmentation technique is the only one that allows studies closeto the neutron dripline for above mass 10
Inflight + StoppingUse fragmentation to produce beam, stop beam in gas, extract products ofinterest, reacclerate and then use at energy you wantFor example, with fast beams only Coulomb excite first 2+ but withlow energy beams could observe first 3- etcTheory of transfer reactions for low energies( ~10 MeV/amu)is well developed so can extract information on location ofsingle particle levels to search for predicted decrease of spin-orbitstrength at neutron driplineYou can trap very exotic nuclei and search for exotic effects like anapole moments
