    "abstract": "The interaction of 3-level system with a quantum field in a non-equilibrium\nstate is considered. We describe a class of states of the quantum field for\nwich a stationary state drives the system to inverse populated state. We find\nthat the quotient of the population of the energy levels in the simplest case\nis described by the double Einstein formula which involves products of two\nEinstein emission/absorption relations. Emission and absorption of radiation by\n3-level atom in non-equlibrium stationary state is described.",
