超音速分子ビームによる表面化学反応の放射光光電子分光観察

Synchrotron radiation photoemission study on surface chemical reactions facilitated by supersonic moleculra beams

吉越 章隆 

Yoshigoe, Akitaka

本招待講演では、SPring-8のJAEA専用軟X線ビームラインBL23SUに設置した表面反応解析装置を使った研究を紹介する。超音速分子線により引き起こされる表面反応の放射光リアルタイム光電子分光によるその場観察のいくつかの結果を紹介する。また、分子の並進運動エネルギーを変えることによって露となる表面吸着反応ダイナミクスを紹介する。本手法のナノスケールの表面プロセスの基礎および応用研究における有用性と将来展望を述べる。

In this invited talk, surface chemistry researches for various applications, which have been conducted by using surface reaction analysis apparatus constructed at JAEA soft X-ray beamline (BL23SU) of SPing-8 are presented. Several results on in situ synchrotron radiation photoemission analysis of surface reactions induced by supersonic molecular beams are mainly talked. Furthermore, the studies on surface reaction dynamics which is clarified by the experiments of incident energy dependence are also presented. The usefulness of our experimental approaches applying to various surface processes and future perspectives of theses research fields will be talked based on basic sciences and technologies viewpoints.
