By using a MICE detector and a new technique for representing convolution integrals, they have been able to make precision measurements of the interference parameter and isomer lifetime for the 46.5 keV gamma transition in /sup 183/W. Because the signal-to-background obtained by this technique is a factor of 20 greater than for conventional transmission Moessbauer spectroscopy, the present results indicate that a new level of accuracy in time reversal invariance studies using the Moessbauer approach may be possible, giving a critical test of some of the theories of T breakdown involving possible fifth forces in nature. The measured interference parameter is in very good agreement with theory.
