Abstract

The experimental investigations of the polarization transport in the disordered spin system8Li −6Li in LiF crystal are considered. This process is initiated by one originally polarized beta-active8Li nucleus produced in a nuclear reaction. The autocorrelation function Foo(t) for the ran dom-walks-in-disordered-system problem has been measured over the range Foo(t)≥0.1 Foo(0) by analysing the β-emission anisotropy. The influence of the resonance process at double larmor frequency and of the thermal translational motion of8Li and6Li spins is studied. Results are in a good agre ement with the theory.
