The 3rd International Conference on Ion Formation from Organic Solids (IFOS III) was held at the University of Munster, September 16-18, 1985. The conference was attended by 60 invited scientists from all over the world. Of the 43 papers which were presented, 40 are included in these proceedings. The aim of IFOS III was to promote the exchange of results and new ideas between scientists actively working in the field of mass spectrometry of involatile materials. Various aspects of the ion formation process - realization and optimization, theoretical understanding and analytical application...

This volume contains the proceedings of the Fifth International Confer- ence on Secondary Ion Mass Spectrometry (SIMS V), held at the Capitol Holiday Inn, Washington, DC, USA, from September 30 to October 4, 1985. The conference was the fifth in a series of conferences held bienni- ally. Previous conferences were held in Miinster (1977), Stanford (1979), Budapest (1981), and Osaka (1983). SIMS V was organized by Dr. R. J. Colton of the Nayal Research Lab- oratory and Dr. D. S. Simons of the National Bureau of Standards un- der the auspices of the International Organizing Committee chaired by...

Die physikalischen und chemischen Eigenschaften einer Fest korperoberflache werden von ihrer Zusammensetzung im Bereich der obersten Atomlagen bestimmt. Eine moglichst genaue Kennt nis der chemischen Zusammensetzung der Festkorperoberflache ist Voraussetzung fur das Verstandnis vieler technisch wich tiger Bereiche wie z. B. Katalyse, Korrosion und Dunnschicht technik. Ein Verfahren zur Oberflachenanalyse, das eine um fassende Information uber diese Eigenschaften liefert, sollte daher folgende Forderungen erfullen: 1. Anwendbarkeit auf beliebige Proben 2. Informationstiefe im Bereich einer...
