Fig. 2.
The scientific reach with reaccelerated or fast beams of neutron-rich nickel isotopes. Known nuclei and levels are indicated in grey. Unknown nuclei are indicated in orange. Also indicated are nuclei important for the r-process. Investigations that are very far from stability require fast-beam techniques. The gains in sensitivity for fast beams are largely due to the luminosity gains that can be realized with thick targets and, to a lesser extent, are due to forward-focused kinematics.
