Charge radii of neutron-deficient nickel isotopes

ORAL

Abstract

The 56Ni nucleus is doubly magic with the neutron number N = 28, which occurs due to a shell gap driven by the spin-orbit force, but is considered to be a soft core. The mean-square charge radii <r2> were determined for 54,55,56Ni using collinear laser spectroscopy technique at BECOLA at NSCL/MSU to investigate how the softness manifests itself in <r2> at and below N = 28. Details of the experiment and results will be discussed.
