Two slitless Bragg spectrometers were successfully used on a Sun-pointed Skylark rocket flight (SL 304) on May 5, 1966, to measure the solar X-ray emission below 25 Å. The crystals were of potassium ...

Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...

XES is an element-specific method primarily used to analyze the partially occupied electronic structure of materials. The technique is one of the photon-in-photon-out spectroscopies in which an ...

A famous night-sky object has yielded a surprise: a narrow, bar-shaped cloud made of highly ionized iron. The discovery comes from a European team led by astronomers at University College London and ...

Present day oil analysis is done by using optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants and additives in oil samples. This paper ...
