SCIENTIFIC OPPORTUNITIES RARE-ISOTOPE FACILITY 126 WITH A ISOL: Isotope Separator On-Line. A method for producing exotic nuclei in which the nuclei are produced (often by the collision of an energetic light ion with a high Z target)

APPENDIX D 127 Reaccelerated beam: A mode of operation for a rare-isotope facility based on bringing short-lived isotopes to rest using irradiation of targets with a primary beam, and then using a second or "post" accelerator to create beams of these stopped isotopes at the energies required for nuclear science or other applications. Reacceleration can follow either an ISOL or gas catcher ion source method.
