The nuclear resonant scattering (NRS) includes various experimental methods using resonant excitation and scattering process of nuclei by the synchrotron radiation (SR). The NRS is widely applied to various research areas as a cutting-edge method with outstanding properties of SR, which is not only advanced method but also beyond the conventional Mossbauer spectroscopy. The NRS Research Group have been supporting the developments of the experimental methods and further applications of the various advanced methods, which have excellent properties of NRS spectroscopies with isotope selectivity, ultra-high energy resolution, high time resolution, and so on. The objective of the Research Group includes various methods, such as the SR-based Mossbauer absorption spectroscopy, which is advanced Mossbauer spectroscopy used for various elements; the nuclear resonant inelastic scattering, also known as nuclear resonance vibrational spectroscopy for element-specific phonon studies; the synchrotron Mossbauer source, which is highly brilliant 57Fe Mossbauer source using the nuclear monochromator; the nuclear resonant quasi-elastic scattering for dynamics studies of soft matters; and ultra-precise nuclear excitation studies aiming for the nuclear clock. One of the principal Research Group activities is to promote these studies and enhance the research outputs by improving and supporting the experimental environments such as beamline hardwares in optics and detecting systems, data acquisition and measurement control softwares, developments for huge data handling system, etc. Moreover, the Group supports for activation of the NRS researcher community by increasing new users, improvement of experimental skills of each user, promote mutual interaction of users. In this term of the Group activity, effective use of SPring-8-II upgraded beams, improvements to experimental environments suitable for the upgraded beams, suitable targets for research activities, coordination of differences in users’ visions, and requests for upgraded beam specifications will be discussed.
