    "abstract": "A model of particle interacting with quantum field is considered. The model\nincludes as particular cases the polaron model and non-relativistic quantum\nelectrodynamics. We compute matrix elements of the evolution operator in the\nstochastic approximation and show that depending on the state of the particle\none can get the non-exponential decay with the rate t^{-3/2}. In the process of\ncomputation a new algebra of commutational relations that can be considered as\nan operator deformation of quantum Boltzmann commutation relations is used.",
