Towards measurement of charge radii of neutron-deficient <sup>52,53</sup>Ni
ORAL
Abstract
Chains of charge radius of Ca and Ni isotopes show a similar trend across the neutron magic number N = 28, though 48Ca is known to be a robust doubly-magic nucleus, whereas 56Ni is soft as a doubly-magic nucleus [1]. The charge radius measurements will be extended to very neutron-deficient 52,53Ni isotopes to investigate if the surprising similarity persists and for better understanding of structure around the soft 56Ni. The experiment will be performed at the BECOLA/RISE facility at FRIB. Currently, test experiments are performed to establish an efficient, low-background multi-step laser resonant ionization scheme using a Rydberg state as a final state to be ionized via field ionization. Details of the development as well as the science background will be discussed.
