Loftus, Stuart … WebFull spectrum fitting is the most appropriate gamma ray spectral analysis technique for BECA, given the limited energy resolution of the CeBr GRS. Rather than measuring the counts in individual gamma ray spectral lines, a weighted least squares fit is performed on the 0.7 - 10 MeV gamma ray spectrum as a whole
WebApr 11, 2024 · X-ray binaries, as bright local sources with short variability timescales for a wide range of accretion processes, represent ideal targets for high-resolution X-ray spectroscopy. In this chapter, we present a high-resolution X-ray spectral perspective on X-ray binaries, focusing on black holes and neutron stars. The majority of the chapter is …
WebSpectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of astronomy, chemistry, materials science, and physics, allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over astronomical distances.
Raman spectroscopy (named after Indian physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. Raman spectroscopy is commonly used in chemistry to provide a … See more The magnitude of the Raman effect correlates with polarizability of the electrons in a molecule. It is a form of inelastic light scattering, where a photon excites the sample. This excitation puts the molecule into a See more Raman shifts are typically reported in wavenumbers, which have units of inverse length, as this value is directly related to energy. In order to … See more Raman spectroscopy is used in chemistry to identify molecules and study chemical bonding and intramolecular bonds.
