Abstract

In problems involving transitions between two decaying states, one encounters lorentzian factors whose width is given by the sum of the decay rates from the two states in question, i.e. by the natural linewidth. In the present paper, we discuss techniques for achieving resolution beyond the natural linewidth, limited by the difference between the decay rates rather than their sum. These techniques provide the possibility of enhanced spectral resolution, as well as giving a direct measurement of the difference between the decay rates.
