Abstract

The

2 s

and

3 s

contributions to the core polarization at the nuclear site of

{}^{57}{Fe}

{Fe}_{2}

O_{3}

films was measured by internal-conversion electron Mössbauer spectroscopy with a new high-transmission, high-resolution electrostatic electron spectrometer. The spin-density ratios

δ_{ns} = \frac{{| ψ_{ns}^{↑} (0) |}^{2}}{{| ψ_{ns}^{↓} (0) |}^{2} - 1}

δ_{2 s} = - 0.0048 (7)

, and

δ_{3 s} = + 0.0149 (33)

were determined.
