In nuclear spectroscopy conversion electrons have been counted with energies as low as 20 kv arising from an excitation process having a cross section of the order of 10−34 (cm2). The special requirements of counters for such purposes are reviewed and a description is given of several self‐quenching counters which have proven useful in a study of nuclear spectra. A simple and rapid method of filling these counters is also described.
