Abstract
The scattering of light at small angles (not Rayleigh) and the dependence of the refractive index of silica aerogel produced by the Matsushita Electric Works (Japan) on wavelength were investigated in the range of interest for Ring Imaging Cherenkov detectors (RICH). In the λ-interval 350–650 nm, the aerogel refractive index decreases by 0.15%, the average forward scattering angle of light in traversing aerogel varies from 1.2 to 2.2 mrad, and the fraction of forward scattered light per cm of aerogel varies from 20% to 8%.
