Differential ionization chambers are used in order to measure the difference in the electron capture rate of 52Fe nuclei in different chemical compounds. Combination with the corresponding Mössbauer isomer shifts of these Fe compounds permits the determination for the Mössbauer transition in 57Fe of Δ〈r2〉=-(33±3)10-3 fm2.
