The wavelength of the 57Fe Mössbauer radiation is measured with a relative uncertainty of 0.19 ppm by using almost exact Bragg backscattering from a reference silicon crystal. Its value is determined as lambda(M) = 0.860 254 74(16)x10(-10) m. The corresponding Mössbauer photon energy is...
Gamma-Ray Observatories are scientific facilities in space that detect and study high-energy gamma-ray emissions from celestial sources, providing valuable data on a wide range of astronomical phenomena such as Active Galactic Nuclei and blazars. AI generated definition based on: Advances in Space Res...
The first part of the chapter would elaborate on the gamma-ray processing of foods and its applications in the disinfection of fruits, treatment of drinking water, disinfestation of cereals and sterilization of meat and poultry products. Further, physicochemical characteristics of treated products and ...
What is the frequency of gamma ray radiation that has a wavelength of 1.00 x 10−16 m? Frequency = sec−1. Gamma Rays: Gamma rays are a form of electromagnetic radiation. Gamma rays have the highest energy within the electromagnetic spectrum. Consequentl...
The current status of observations and theoretical models of gamma-ray bursts and some other related transients, including ultra-long bursts and tidal disruption events, is reviewed. We consider the impact of multi-wavelength data on the formulation and development of theoretical models for the prompt...

After a short history of optical transient search and the BeppoSAX discoveries, the main topics included are prompt multiwavelength emission, dark bursts, spectral lines line and continuum variability, the early light curve behaviour, jet breaks, X-ray flares, late afterglow features, polarization, ...
As for optical and X-ray transitions, the gamma-ray wavelength λ and diffraction angle θ are related by the Bragg law: nλ = 2d sin θ, where the lattice spacing d is known to an accuracy of 1 part in 1010 and n is the order of diffraction. Clearly, the resolution scales with n...
nm. Transmission drops in the 200–350 nm wavelength range in the UV region due to strong absorption. This happens due to the blend matrix’s Fe+ 3-ion particle size increasing39,40. Pure blend exhibits the maximum optical transmission (roughly 80%). At a wavelength of about 700 nm, ...
Gamma-ray detection and spectroscopy is the quantitative determination of their energy spectra, and is of critical value and critically important in diverse technological and scientific fields. Here we report an improved melt growth method for cesium lea
