Title: First determination of ground state electromagnetic moments of Fe 53

Abstract

The hyperfine coupling constants of neutron deficient 53Fe were deduced from the atomic hyperfine spectrum of the 3d64s25D4↔3d64s4p5F5 transition, measured using the bunched-beam collinear laser spectroscopy technique. The low-energy 53Fe beam was produced by projectile-fragmentation reactions followed by gas stopping, and used for the first time for laser spectroscopy. Ground state magnetic-dipole and electric-quadrupole moments were determined as μ=-0.65(1)μN and Q=+35(15)e2fm2, respectively. The multiconfiguration Dirac-Fock method was used to calculate the electric field gradient to deduce Q from the quadrupole hyperfine coupling constant, since the quadrupole coupling constant has not been determined for any Fe isotopes. Both experimental values agree well with nuclear shell model calculations using the GXPF1A effective interaction performed in a full fp shell model space, which support the soft nature of the 56Ni nucleus.

FIG. 1 FIG. 1: The BECOLA facility. Fe+ ions are sent to the RFQ cooler/buncher from either the PIG ion source or the online beam. Following the cooler/buncher, the ion beam is overlapped with the laser light, and sent through a charge-exchange cell (CEC) containing sodium vapor. The laser-resonant fluorescence from themore » neutral atoms is collected using an elliptical mirror and detected by a photomultiplier tube (PMT). The static potential applied to the RFQ cooler/buncher and the scanning potential applied to the CEC were recorded with high precision using two digital voltmeters (DVMs).« less
