Atomic Resolution g-ray Holography Using the Mössbauer Effect
نویسندگان
چکیده
We have observed a strong (2%) angular modulation of the total backscattered conversion electron yield, measured as a function of the incidence angle of the 14.4 keV g rays from a 57Co Mössbauer source irradiating thin epitaxial 57Fe film grown on MgO(001). The measured 2D pattern is the first hologram of the local surrounding of the absorbing nuclei obtained due to nuclear resonant scattering of g rays. The real space holographic reconstruction shows distinct features corresponding to the nearest neighbor sites in the bcc a-Fe structure. [S0031-9007(97)04412-8]

Complex gamma-ray hologram: solution to twin images problem in atomic resolution imaging.
A new technique for high fidelity three-dimensional imaging of atomic structure with gamma-ray holography is demonstrated. A complex hologram was constructed from holograms recorded for different values of the nuclear scattering amplitude on both sides of the (57)Fe Mössbauer resonance. The holographic reconstruction was applied to this complex hologram resulting in a twin-image-free image of t...
متن کاملThe Free Electron Laser: Properties and Prospects
Novel electron accelerator techniques can be used to create free electron lasers in a wide wave length interval extending to the X-ray region, i.e. providing an X-ray laser. Due to the coherent emission, very large intensities can be obtained, with peak brilliance ten orders of magnitude higher than in conventional synchrotron radiation. This opens completely new prospects for sciences that stu...
متن کاملLattice Imaging in Transmission Electron Microscopy
With the resolution becoming sufficient to reveal individual atoms, high-resolution electron microscopy (HREM) can now compete with X-ray and neutron methods to determine quantitatively atomic structures of materials, with the advantage of being applicable to non-periodic objects such as crystal defects. An introduction to the theory and practical aspects of HREM is given. Principles of other l...
متن کاملSoft x-ray coherent magnetic scattering experiments
The increased coherence of third generation synchrotron sources allows us to port laser techniques such as holography and dynamical light scattering from the visible to the x-ray spectral range. In addition to the obvious improvement in resolution, the x-ray range may allow for new variants that are not possible in the visible, as exemplified by techniques that use the strong magnetic contrast ...
متن کاملAtomic string holography.
A new diffraction-channeling effect has been discovered, in which Kikuchi or channeling line patterns formed by high energy electrons, neutrons, and positrons are shown to break up into a series of annular disks if the crystal thickness traversed by the beam is small. The disks may be interpreted as Gabor in-line holograms of strings of atoms projected along the beam path. For electrons or posi...
