Discrete spectral shift in an anisotropic universe

Abstract
In this paper we calculate the particle creation as seen by a stationary observer in an anisotropic universe. By using an observer and geometry dependent time to quantise a massive scalar field we show that a discrete energy spectrum shift occurs. The length scale associated with the geometry provides the energy scale by which the spectrum is shifted. The coefficient for the Bogolubov transformation calculated is proportional to a series of delta functions whose argument contains and and half multiples of the root of the curvature.
