An adapter for single channel analyzers has been built which reduces the time jitter in the output of an analyzer by a factor of approximately six. This reduction enables coincidence studies to be conducted using a correspondingly smaller 2τ which results in an approximate sixfold increase in the true to accidental coincidence ratio. In addition the use of a smaller 2τ permits the measurement of significantly shorter halflives of metastable states than is possible without the use of adapters when only a simple coincidence circuit is utilized.
