Abstract

A Parallel Plate Avalanche Counter （PPAC） with weighted about 40 g was developed for isotope separator on-line Moessbauer Spectroscopy. It detects the internal conversion electrons emitted from the resonance Moessbauer nuclide. The signal-to-noise ratio of the spectra reaches 11 for 85% enriched ^119SnO2 cathode and absorber. It is an effective detector for on-line Moessbauer experiments. The perform ance of the counter was discussed in detail.
