METASTABLE TRANSITIONS AND ISOTOPE DISTRIBUTION IDENTIFICATION PROGRAM FOR USE IN MASS-SPECTROMETRY INVOLVING SPECTRA WITH MULTIPLE COINCIDENCES

We have developed a user program-written in JPI Top Speed Modula2 for IBM-AT compatible computers-which allows one to predict and identify, for a given cluster ion series, possible coincidences in (i) the ordinary mass spectrum and (ii) for metastable and collision-induced decay reactions in the first and second field-free regions of a double focussing sector field instrument. The capability of this program will be demonstrated by discussing several selected examples. The program may be obtained free of charge from the authors.
