The amount of scattering from objects is linked to the relation between the radiation wavelength and the composition of the objects. When the object surface roughness and the particulate composition is of the order of the radiation wavelength, scattering dominates. However, for longer wavelengths, ...
(atomic absorption line), then σ ~ ω4, or λ-4, where λ is the wavelength of the light. This relation, found on the. basis of the concept of the atom as an electric dipole oscillating in the field of the light wave, is called Rayleigh’s law. The cross sections increase sharply...
This one-of-a-kind book presents many of the mathematical concepts, structures, and techniques used in the study of rays, waves, and scattering. Panoramic in scope, it includes discussions of how ocean waves are refracted around islands and underwater ri
Measurements have been made of the transmission of neutrons of wave-lengths between 5 and 10 through 10 cm of unirradiated and pile irradiated Brazilian quartz crystals. The total transmission cross section of the unirradiated crystal varied as [sgrave]A=0.55+1.63 in the measured wavelength range...
1). The wavelength of the incident X-ray is 1.239 Å. The charge-coupled device (CCD) detector, placed perpendicular to the incident beam, is used to record the 2D GISAXS patterns. The PNSs in solution are first characterized by small-angle X-ray scattering (SAXS) and the one-...
Resonance Rayleigh scattering (RRS) is special elastic scattering that occurs when the wavelength of Rayleigh scattering is located at or near to the wavelength of the molecular absorption. From: Microchemical Journal, 2023 About this pageAdd to MendeleySet alert ...
absorption. Light scattering is a physical characteristic of proteins in suspension when the protein exists in particulate sizes from 0.001μm to 1.0μm in the greatest dimension. Two of the factors affecting light scattering are the particle size and wavelength of the light source or incident ...
Here we experimentally measure high-harmonic spectra from liquid water and alcohols over a broad range of laser wavelengths. We observe that the HHG cut-off energy (Ec), that is, the energy marking the end of the plateau region as defined in the Lewenstein formalism2, is wavelength-independent...
Importantly, this experiment yields some fantastic outcomes that the scattering lens with a coherent-state input can achieve a sub-100 nm resolution at visible wavelength, better than that of the conventional lens (an optimal resolution of order of around 200 nm at visible wavelength1). Although ...
The samples for the 2D CC demonstration experiment consisted of a large number of nominally identical 2D gold nanostructures, anchored to a membrane, with random positions and orientations (Fig. 1d). The membrane was scanned through a focused X-ray beam of 2 Å wavelength, and the scattering...
