Here, besides the MEH-PPV diffraction peaks, broad X-ray peaks attributed to the formation of CdS nanocrystals are also observed.
The coatings showed a random crystal orientation with broad X-ray diffraction peaks and had a very dense and fine-grained structure.
Astrosat will be the first full-fledged Indian Astronomy mission aimed at multiwavelength studies in the optical, near- and far-UV and a broad X-ray spectral band covering 0.5 100 keV.
However, it should be noted that it is not possible to distinguish among the materials which are (a) truly amorphous and (b) extremely refined grain by observing the broad X-ray peaks alone [3], especially in the ball-milled samples.
Powerful third generation synchrotrons are now available to deliver broad X-ray beams (10 100 keV), brilliant enough for using monochromators and able to precisely select the desired X-rays energy.
This makes the technique capable of mapping in conjunction with either an X-ray microprobe, in which case the detector can be based on a light collection system and a device such as a broadband photomultiplier, or a broader X-ray beam (such as that from a bending magnet) when an imaging detector such as a CCD camera is required.
The diagnosis of tuberculosis in patients with negative smear results conformed to the NTP guidelines (no clinical response to 14 days' treatment with broad spectrum antibiotics and chest x ray picture suggestive of active tuberculosis).
The energy of the broad incoming x-ray beam is stepped across an absorption edge of the chemical element under investigation in, typically 100 or more small increments.
Properties of the transient/persistent emission are summarized and the broad band X-ray spectra discussed in detail for a few sources.
The spectrum includes broad bremsstrahlung X-rays with energies of up to 50 keV and a few characteristic X-rays at 8.4, 9.7, and 11.3 keV that respectively correspond to Lα1, Lβ1, and Lγ1 of the W target [21].
Here we report an analysis of the broad band x-ray spectrum of the x-ray burst source Aquila X-1 during a "mini-outburst" (peak flux < 0.25 mCrab) in which hard x-rays were detected out to at least 100 keV.
