| Outline of Final Research Achievements |
In this study, it is demonstrated that the dissociation pattern and the threshold of bond dissociation is determined depending on molecular structure (type of functional group) and irradiation condition of cluster ion (Eatom, cluster size etc) from the experimental results of multiple polymer samples.
In addition, we made possible to acquire a large amount of spectral data in a short time, so that the statistical error of analysis could be reduced. As a result, it is suggested that information of chemical structure of molecules is included in the Eatom dependency data of the SIMS spectrum. In the future, we will establish the basic idea of complicated spectrum analysis method by the multivariate analysis based on the secondary ion spectrum obtained from samples with different chemical structure.
