Pileup losses in nuclear pulse spectrometry also depend on energy as lower energies produce narrower pulses which in turn
have better chances to avoid pulse pileup. Consequently, in our present system individual energy-dependent pileup correction
factors are calculated for all events, making it what very probably may be called the first perfect implementation of Loss-Free
Counting. Temporal response and quantitative performance of the new system are tested over the whole range of counting rates
(up to 106 c/s) and counting losses (up to 99%) by means of short-lived isomeric transitions and a fast rabbit system.
