The International X-ray Absorption Society (IXAS) is an international scientific organization representing all those working with X-ray Absorption Spectroscopy, and especially the detailed structure associated with inner shell excitation by X-rays and electrons. XAS includes XANES (X-ray Absorption Near-Edge Spectroscopy) and EXAFS (Extended X-ray Absorption Fine-Structure) but also includes related methods in which an X-ray or electron has enough energy to remove a core-level electron from an atom. All of these methods share a physical basis and many methods for measuring and interpreting the data.

The mission of the IXAS is to promote the research activities of XAS and related phenomena as a multi-nation non-profit organization and to coordinate community activities that benefit the community of people using XAS. The IXAS establishes committees, fosters education, and shares relevant information about analytical methods. It also works with other related regional, national and professional organizations in promoting and developing XAS and related disciplines. The IXAS has several projects which are performed by the IXAS Executive Committee (EC) officers and members, including:

Selection of International XAFS Conference
Soliciting IXAS Awards
Information exchange through the official website

This set of web pages give information about the X-ray absorption Spectroscopy, the IXAS organization, and activities related to XAS. The site is a continual work-in-progress and your feedback and suggestions are welcome.
