Abstract: The oscillations of the vacuum angle 8 due to a cosmological axion field will induce oscillating electric dipoles onto nuclei. We discuss the observability of the resulting nuclear dipole radiation.The a~i o n ' ,~ is generally thought to be the most attractive solution to the strong CP problem. Nevertheless, no positive hint for its existence has been obtained so far. The many experiments carried out during the last decade essentially rule out the so-called visible-axion models including the Peccei-Quinn-Wei…
