Abstract
Abrupt pulse height changes and different steady state pulse heights exhibited at particular count rates are observed reproducibly in RCA 8850 and 8575 tubes. These phenomena are shown to be identical in nature with the hysteresis effect observed previously in a different type of tube. The implications for a standard count rate stability test and precision scintillation counting experiments are briefly discussed.Keywords
