Abstract
The steady state of a pair of isotopes resulting from the incoherent process of excitation-de-excitation and spontaneous decay is found. When the applied magnetic field corresponds to resonance between Zeeman sublevels in the pair, simultaneous spontaneous decay induces interatomic correlations. The resulting state belongs to the class of states with positive partial transpose. One consequence of the correlations is a redistribution of the probabilities for the directions of spontaneous emission at the resonant transition frequency.
