X-ray monochromator system for use with synchrotron radiation sources
(AIP Publishing, 1981)
A double crystal x‐ray monochromator system has been developed for use on synchrotron radiationsources. The system consists of two separate Bragg reflecting crystals constrained by a mechanical linkage system enabling it ...
Coherent Compton Effect
(American Physical Society (APS), 1981)
Interference effects have been observed when coherently related x-ray beams are Compton scattered from an atomic system. We use dynamical diffraction methods to prepare the initial x-ray state and observe the coherent ...
Arsenic atom location on passivated silicon (111) surfaces
(American Physical Society (APS), 1987)
The position of As atoms on a clean Si(111) surface has been determined with x-ray standing waves in ultrahigh vacuum. The As atoms occupy exclusively the top half of the silicon (111) double plane and lie at 0.17 Å above ...
New Reconstructions on Silicon (111) Surfaces
(American Physical Society (APS), 1986)
We report the first observation of a class of new reconstructions on clean silicon (111) surfaces. The surfaces are prepared by a combination of laser and thermal annealing and the new structures are studied with a tunneling ...
