Through the looking glass: probing the nucleus using accelerated radioactive beams

“…An important experimental programme at REX is the systematic measurement of low-lying collectivity in neutron-rich nuclei having N=40-50. P. Mayet et al [6] have reported in this conference the first measurements of B(E2:0 g → 2 1 ) values in 74,76 Zn; this same collaboration has recently measured this quantity in 78 Zn.…”

“…The total cost of such a facility has been estimated as 600 M euros, including buildings but excluding manpower. The high-intensity of 6 He and 18 Ne beams available would make EURISOL an attractive source of β-unstable nuclei for an electron neutrino facility ('beta-beam', see next sub-section), see figure 2.…”

“…The muons are subsequently cooled and accelerated before injection into a bow-tie or triangle shaped decay ring. A new concept for neutrino beams having strong synergies in accelerator and target technology with a RIB facility is the beta-beam [14] in which 6 He and 18 Ne radioactive ions are accelerated to a Lorentz gamma of ≈ 100 before injection into a decay ring, thus producing a flavour-pure beam of antineutrinos and neutrinos respectively. The high duty cycle of the CERN SPL (at least 150 µs available of the 2.8 ms pulse width, repeated at a frequency of 50 Hz) provides a good match to the specification of the primary driver of EURISOL.…”

Gamma-ray spectroscopy with relativistic exotic heavy-ions

“…Such studies can be broadly classified as: i) decay spectroscopy and ii) in-beam spectroscopy. The angular momentum induced in fragmentation reactions at relativistic energies is sufficiently large [2,3] to perform a meaningful high spin decay spectroscopy of exotic nuclei. At the same time relativistic Coulomb excitation using a radioactive beam from the fragmentation reaction offers an excellent tool to probe the structure of exotic nuclei at low spin.…”
