The IGLIS-NET is an international network for exchanging current development information on the research field of IGLIS (In-Gas Laser Ionization and Spectroscopy) between participating research groups. Primarily motivated as a collaboration network between Japan (KEK and RIKEN) and Belgium (KU Leuven) on the development of the IGLIS method for the study of r-process nuclei, the IGLIS-NET is initially constituted by 15 participating research groups and institutes. The scopes include not only technical issues related to the IGLIS method but also more general aspects about related topics in physics from a technical point of view. Frequent exchange of the communications among these participants will be promoted through this website. Furthermore, the documentations of scientific publications on the scopes defined in the IGLIS-NET will be made.
