Abstract
The nuclear quadrupole moment of the I=3/2- excited nuclear state of 57Fe at 14.41 keV, important in M\"ossbauer spectroscopy, is determined from the large-scale nuclear shell-model calculations for 57Fe and also from the electronic ab initio and density functional theory calculations including solid state and electron correlation effects for the molecules Fe(CO)_5 and Fe(C_5 H_5)_2. Both independent methods yield very similar results. The recommended value is 0.16(1) eb. The NQM of the isomeric 10+ in 54Fe has also been calculated. The new value (0.5 eb), consistent with the perturbed angular distribution data, is by a factor of two larger than the currently recommended value.
