Title: Nuclear Quadrupole Moment of F

Abstract

The nuclear quadrupole moment (NQM) of the I{sup {pi}}=3/2{sup -} excited nuclear state of {sup 57}Fe at 14.41keV, important in Moessbauer spectroscopy, is determined from the large-scale nuclear shell-model calculations for {sup 54}Fe , {sup 57}Fe , and also from the electronic ab initio and density functional theory calculations including solid state and electron correlation effects for the molecules Fe(CO){sub 5} and Fe(C{sub 5}H{sub 5}){sub 2} . Both independent methods yield very similar results. The recommended value is 0.15(2)eb. The NQM of the isomeric 10+ in {sup 54}Fe has also been calculated. The new NQM values for {sup 54}Fe and {sup 57}Fe are consistent with the perturbed angular distribution data.
