Quadrupole Moment of 57Fem
NOTE: At the time of publication, the author Richard B. Frankel was not yet affiliated with Cal Poly.
The quadrupole splitting induced by a magnetic field at low temperatures has been measured by Mössbauer spectroscopy for Fe2+ in MgO; a value of +0.21 ± 0.03 barn for the quadrupole moment of 57Fem is obtained.
