(Received 12 April 2005; published 10 August 2005)

A scheme in which a velocity drive serves as an interferometer and phase shifter in nuclear resonant scattering experiments is presented, and a straightforward algorithm for phase determination is developed. The experimental feasibility of the concept is demonstrated for nuclear forward scattering by an alpha-iron foil for different directions of the hyperfine field. It is also shown that the obtained phase information can be used for the reconstruction of the energy spectrum.

  21. The contribution of electronic scattering can be described by a scaling factor. Since this factor is the same for both scattering paths, it can be omitted without loss of generality.
  22. The phase difference phisigma(t0)+omegart0 is the difference in phase due to the nuclear resonant scattering process; this technique is not sensitive to the phase change due to electronic scattering.
  23. Thirty-seven percent of the data is located in this excluded region.
