[1] Soft X-ray emission has been observed from the low-latitude disk of both Jupiter and Saturn as well as from the auroral regions of these planets. The disk emission as observed by ROSAT, the Chandra X-Ray Observatory, and XMM-Newton appears to be uniformly distributed across the disk ...
Soft-x-ray emission from a cryogenically cooled Ne jet irradiated by intense, 25-fs laser pulses was measured. The Ne spectrum started to drastically change in emitting ions from Ne5+ to Ne7+ below the preexpansion temperature of -120 degrees C. The significant change in the spectrum is at...
The distinct processes are involved in X - ray emission. X 射线的发射,包含两种不同的过程. 辞典例句 Doctors discovered the hematoma by using a special computer X - ray called a " ket - skein ". 医生们使用了一种叫 “ 铜束 ” ( ket -skein)的特别的电脑x光机,检查出了脑血肿的准确位置....
even in the ultrarelativistic limit, strongly depends on the ratio of laser intensity to plasma density and exceeds the frequently quoted value of −8/3 over a wide range of parameters. The coherent synchrotron emission model, when adequately corrected for the finite width of emitting electron ...
The X-ray Emission Survey of the Taurus Molecular Cloud (XEST) is an exceptionally large project to systematically investigate the high-energy properties of young stellar objects in this nearest star-forming region. It is accompanied by optical and near-infrared surveys of the same area. When XM...

(microscopic) proton-induced X-ray emission (μ-PIXE). It should be noted, however, that manyEPXMAinstruments are also equipped with WD detectors (e.g., for low-Zelement analysis). Important variants of the conventional XRF technique that have achieved considerable success in recent years are...
Flare star, any star that varies in brightness, sometimes by more than one magnitude, within a few minutes. The cause is thought to be the eruption of flares much larger than, but otherwise similar to, those observed on the Sun. Flare stars are sometimes
With the advances of high photon flux at new-generation synchrotron radiation facilities, advanced X-ray spectroscopies with high-energy resolution, such as high-energy-resolution fluorescence-detected XAS (HERFD-XAS), nonresonant X-ray emission spectroscopy (XES) and resonant inelastic X-ray scatterin...
