Charge radius of neutron deficient <sup>54</sup>Ni and symmetry energy constraints using the difference in mirror pair charge radii

ORAL

Abstract

The charge radius of 54Ni was determined for the first time using collinear laser spectroscopy at the BEam COoling and LAser spectroscopy (BECOLA) facility. Combined with the known charge radius of its mirror partner 54Fe, the slope L of symmetry energy in the nuclear equation of state was determined. The details of the experiment and the mirror-radius analysis will be presented. Also, the obtained L will be compared with that obtained from the neutron star merger GW170817 and PREX-2.
