Radioactive Ion Beam Production Capabilities At The Holifield Radioactive Ion Beam Facility

Physics with REX-ISOLDE: from experiment to facility

“…The inelastic proton branch, identified through coincidences between a proton group at 2.26 MeV and 495 keV γ-rays detected in the Miniball array, was consistent with a strong inelastic proton branch approximately equal in intensity to the ground-state branch. Combining this result with other experiments [95] it appears that 14 O will be destroyed through the (α,p) reaction in X-ray bursts, but not in novae, and that the inelastic branch will indeed make a significant contribution.…”

“…Experiments that are mainly motivated by astrophysics questions are a small component of the physics program at REX-ISOLDE compared to other facilities presented in this volume [4,95,109]. Some of the advancements of our knowledge on nuclear structure mentioned above will of course also improve the reliability of nuclear astrophysics calculations, see also [110].…”

“…Data were obtained with beams from even mass 122−126 Cd, 138−144 Xe and 140,142 Be isotopes [94]. These experiments were partially triggered by a surprising result obtained at the Oak-Ridge radioactive beam facility [95,96]. Experiments using neutron-rich tin and tellurium beams in the vicinity of 132 Sn showed a deviation from the simple picture that the product of the energy of the first 2 + state with B(E2)-value can be described by a simple formula, the so-called Grodzins' formula [97].…”

“…The RILIS is particularly useful for purifying RIBs that have large isobaric contamination but no effective ion selection method. The second ISOL production platform at the former HRIBF, Injector for Radioactive Ion Species 2 (IRIS2) [1,11], was designed to enable the use and development of various beam purification techniques such as RILIS, ion beam cooling [3], and selective photodetachment [5]. The RILIS is based on a hot-cavity ion source and all-solid-state Ti:Sapphire lasers.…”
