Charge radii of neutron-deficient $^{52, 53}$Fe
ORAL
Abstract
Shell closures can be identified as “kinks” in the chain of charge radii, $\left< r^2\right>$, which can be seen for the $N$ = 28 neutron shell closure up to $_{25}$Mn. The $\left< r^2\right>$ trends in the vicinity of $^{56}$Ni is of particular interest, since the $^{56}$Ni nucleus is known to be soft. The $\left< r^2\right>$ of neutron-deficient $^{52, 53}$Fe were determined in the present study using the bunched beam collinear laser spectroscopy at BEam COoling and LAser spectroscopy (BECOLA) facility at NSCL/MSU. The presence of a kink in the chain of $\left< r^2\right>$ at $N$ = 28 for the Fe isotopes was confirmed. The global behavior of the $\left< r^2\right>$ of Fe, and Ca thorough Ni isotopes, will be discussed.
