Quantum motion of a neutron in a wave-guide in the gravitational field [PDF]

, 2005
We study theoretically the quantum motion of a neutron in a horizontal wave-guide in the gravitational field of the Earth. The wave-guide in question is equipped with a mirror below and a rough absorber above. We show that such a system acts as a quantum

On The Reddening in X-ray Absorbed Seyfert 1 Galaxies [PDF]

, 2000
There are several Seyfert galaxies for which there is a discrepancy between the small column of neutral hydrogen deduced from X-ray observations and the much greater column derived from the reddening of the optical/UV emission lines and continuum.
