    "abstract": "We study theoretically the quantum motion of a neutron in a horizontal\nwave-guide in the gravitational field of the Earth. The wave-guide in question\nis equipped with a mirror below and a rough absorber above. We show that such a\nsystem acts as a quantum filter, i.e. it effectively absorbs quantum states\nwith sufficiently high transversal energy but transmits low-energy states. The\nstates transmitted are mainly determined by the potential well formed by the\ngravitational field of the Earth and the mirror. The formalism developed for\nquantum motion in an absorbing wave-guide is applied to the description of the\nrecent experiment on the observation of the quantum states of neutrons in the\nEarth\u0027s gravitational field.",
