Description:
Author(s): M. Vandebrouck et al. Giant resonances are fundamental excitations of the entire atomic nucleus. This work reports the discovery of several collective isoscalar modes in the unstable neutron-rich nucleus 68 Ni. Such modes are sensitive to the bulk properties of nuclear matter, e.g., how easily nuclear matter can be compressed. The work uses a novel technique with an “active” gas target, in which target and detector are the same. Comparison with lighter nickel isotopes sheds light on how these collective excitations evolve with increasing proton-neutron asymmetry. The experience gained in this work suggests future improvements for the experimental technique. [Phys. Rev. C 92, 024316] Published Fri Aug 21, 2015
