Abstract

Transformation law for the correlation function of nematic aerogel under deformation is found. We propose an approach to describe spin diffusion in 3He confined in deformed aerogel assuming weak correlations. The spin diffusion coefficient anisotropy in the plane, perpendicular to aerogel strands, remains small even for significant deformation.

Key words: nematic aerogel, spin diffusion, liquid 3He.
