A new diffraction technique based on a wide-energy-bandpass X-ray beam in connection with lock-in detection for diffraction studies of crystals subjected to external perturbations has been developed. The broad-energy-bandpass beam is obtained by comb

The d 33 piezoelectric constant of KTiOPO4 (potassium titanium orthophosphate, KTP) has been determined for two different samples and at temperatures between 100 and 220 K, using high-resolution X-ray diffraction of a single-crystal in an electric fi

Rietveld refinement using neutron powder diffraction data for the low-temperature form of strontium tantalum oxide, SrTa 4 O 11 , resulted in R wp = 3.10%. The structure is of the CaTa 4 O 11 type and consists of layers of Ta(2)O 7 pentagonal bipyram

Three different ways of creating a broad energy band X-ray beam have been tested for studying electric field induced changes in Bragg intensities. The basic idea behind all three techniques (graded multi-layer, bent Laue crystal and filtered white be
