โฆ Synopsis
The D$ beam from the moderately high pressure source of a tandem mass spectrometer is reacted with NH3 resulting in formation of NHsD+, NHf and NHzD+. The relative abundance of these products is reported 3s a function of the average number of D$-D2 collisions in the source. This information is used to estimate the amount of excitation energy& the D$ ions.
