Multiply charged ammonia clusters are produced by electron impact ionization of neutral NH, clusters formed by nozzle cxpansion. The properties of these ions are studied with a high-resolution double-focusing sector field mass spectrometer. The observed critical appearance sizes are n, = 5 I and n,
