It is with great sadness that we learned that Professor Jean‐Claude Dousse passed away on June 21st, 2020. Professor Dousse was the former vice‐dean of the Faculty of Sciences and head of the Atomic and X‐Ray Physics Group at the University of Fribourg, Switzerland. He was also a former member of the editorial board of the X‐Ray Spectrometry journal.

Jean‐Claude's contributions to science and the scientific community for over more than 45 years had a significant influence on the advancement of fundamental and experimental atomic physic research. In particular, he pioneered and developed complex instruments such as high‐resolution spectrometers for investigating the various aspects of atomic excitation and decay channels in photon‐atom and charged particle‐atom interaction, or atomic collisions including heavy ions.

Jean‐Claude Dousse received his PhD in Physics from the University of Fribourg, Switzerland, in 1978, and he was immediately appointed as a permanent collaborator there. His research activities were initially devoted to various nuclear reactions on actinides and rare earth nuclei and to muonic physics. In 1982, he won a senior researchers grant from the Swiss National Science Foundation to carry out research in LANL (Los Alamos) and in TRIUMF (Vancouver, Canada) accelerator centers on giant resonances, nuclear reactions, and pionic physics. Back in Switzerland in 1983 and up to 1988, he balanced his teaching activities at the University of Fribourg and his research activities at the Paul Scherrer Institute in Villigen, Switzerland, on nuclear structures and at CERN in Geneva, Switzerland, on antiproton‐nucleus collisions. In parallel, he supervised the elaboration of a new transmission‐type curved crystal spectrometer.

He obtained the habilitation degree for experimental physics from the University of Fribourg in 1986. In 1989, he was appointed as an associate professor for experimental physics and leader of the Atomic and X‐Ray Physics group at the University of Fribourg and he was promoted to the rank of extraordinary professor in 2001. He held the position of the head of the Physics Department from 2005 to 2008, and was the vice‐dean of the Faculty of Sciences from 2012 to 2015. Jean‐Claude retired as head of the Atomic and X‐ray Physics group at the Physics Department of the University of Fribourg in 2017. As Professor Emeritus, he remained active and continued his research collaborations, lecturing, and writing. He contributed to many influential articles, authoring some 150 refereed papers.

Jean‐Claude Dousse was among the scientists who mastered the specialized expertise required in numerous domains after a career moving from nuclear physics to fundamental and applied atomic physics. He excelled at designing and building high‐resolution x‐ray crystal spectrometers, both with transmission and reflection type bent crystals (e.g., Laue‐type DuMond, Bragg‐type von Hamos), and leading experiments that made thorough use of these new designs. He was interested in pushing these instruments to their limits, by combining them with heavy‐ion sources, and intense x‐ray sources such as synchrotrons, or x‐ray free‐electron lasers.

Jean‐Claude Dousse's main research activities were centerd on photo‐induced atomic excitation and decay processes and on multiply ionizing heavy ion‐atom collisions. In fundamental atomic physics, his scientific work was dealing with hollow K‐shell atoms, exotic radiative decay channels of atomic core vacancies such as radiative Auger transitions, the energy‐dependent double photoexcitation of atomic inner‐shells, and the resonant inelastic x‐ray scattering processes (RIXS) including x‐ray resonant Raman scattering (XRRS). He was extremely active in the metrology of x‐ray transitions, where he pursued studies aiming at determining with high‐precision the energies, natural widths, and relative intensities of x‐ray transitions, as well as the determination of fluorescence yields and Coster‐Kronig rates.

His applied atomic physics work was focused on the influence of solid‐state and chemical effects on the x‐ray emission of samples bombarded by photons, electrons, and heavy ions, which modulations can only be detected using high‐resolution X‐ray spectroscopy. In addition, he pushed the development of novel high‐resolution x‐ray spectroscopy techniques such as Grazing Emission X‐Ray Fluorescence (GEXRF) and High Energy Resolution Off‐resonant Spectroscopy (HEROS), for material characterization.

Jean‐Claude Dousse served the X‐Ray Spectrometry in many other ways. He was made an honorary professor at the East China University of Science and Technology in 2008, and he was a member of many national and international science‐advisory panels, scientific associations, and research initiatives such as the International Initiative on x‐ray Fundamental Parameters under the auspices of the European X‐Ray Spectrometry Association (EXSA). He moreover was a respected lecturer, and his collaboration partners were countless.

Professor Dousse was a passionate physicist and performed his work with dedication in both research and teaching. He cared about science, about sharing his technical and scientific competences and about forming a new generation of scientists. Jean‐Claude Dousse was recognized as an excellent and appreciated academic lecturer, and he supervised a large number of MSc and PhD thesis students. As thesis supervisor, he acted as a mentor and was a true academic father. He has left a remembrance imbued with gratitude and a long‐lasting imprint.

His expertise and deep understanding of atomic physic processes, his quiet yet powerful force, and collaborative attitude, made him a well‐known figure in the X‐ray Spectrometry research community, and a respected contributor to conferences and workshops. He will be fondly remembered for his kindness, generosity, and approachableness, for his enthusiasm in never stopping growing in his science and in his life, and for providing support, counsel, and guidance to new generations of physicists. The X‐Ray Spectrometry community has lost a great scientist, a colleague, a mentor, and a friend.For honouring Jean‐Claude Dousse's memory and celebrating his scientific legacy, X‐Ray Spectrometry will launch a special topic selection welcoming contributions in Atomic Physics and X‐ray Spectroscopy. More information will be given soon.
