The low energy coupling of the electromagnetic field to the axion leads to two distinct dispersion relations for the electromagneticaxion oscillations. The one frequency being the normal electromagnetic (E. M.) oscillation while the other represents a coupled oscillation. When a non‐zero chemical potential is associated with the axion‐electromagnetic oscillation and the spectrum of the two oscillations are super‐imposed, a formula emerges that suggests how the Cosmic Background Radiation (C.B.R.) might differ from that of a black body if axions do in fact couple to the background radiation.
