Abstract
We consider a linear Hamiltonian system consisting of a classical particle and a scalar field describing by the wave or Klein-Gordon equations with variable coefficients. The initial data of the system are supposed to be a random function which has some mixing properties. We study the distribution \mu_t of the random solution at time moments t\in\R. The main result is the convergence of \mu_t to a Gaussian probability measure as t\to\infty. The mixing properties of the limit measures are studied. The application to the case of Gibbs initial measures is given.
