Descriptor English: Scattering, Small Angle
Descriptor Spanish: Dispersión del Ángulo Pequeño
Descriptor dispersión de ángulos pequeños
Entry term(s) dispersión de ángulos bajos
Scope note: Dispersión de una RADIACIÓN electromagnética o acústica, o de partículas, en ángulos pequeños a causa de partículas o cavidades de dimensiones que a veces son del orden de varias veces la longitud de onda de la radiación o la longitud de onda de Briglie de las partículas dispersadas. También se denomina ángulo bajo de dispersión (McGraw-Hill Dictionary of Scientific and Technical Terms, 6a ed). Las técnicas de dispersión de ángulo pequeño (SAS), neutrones de ángulo pequeño (SANS), rayos X (SAXS), y dispersión de luz (SALS o simplemente LS) se utilizan para la observación de objetos a escala nanométrica.

Scope note: Scattering of a beam of electromagnetic or acoustic RADIATION, or particles, at small angles by particles or cavities whose dimensions are many times as large as the wavelength of the radiation or the de Broglie wavelength of the scattered particles. Also know as low angle scattering. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed) Small angle scattering (SAS) techniques, small angle neutron (SANS), X-ray (SAXS), and light (SALS, or just LS) scattering, are used to characterize objects on a nanoscale.
