Time-delayed detection in level anticrossing spectroscopy

  • Published:
Il Nuovo Cimento D

Summary

In the present paper we discuss the time-delayed detection of the fluorescence signal in a level anticrossing experiment showing that, unlike what occurs in other methods, it does not lead, in general, to a signal profile narrowing as the delay time increases. However, we find conditions under which this technique provides the possibility of enhanced spectral resolution, as well as gives a direct measurement of the difference between the decay rates of the levels involved.
