Recently, we have succeeded to directly measure the electronic states of “solution” samples under real atmospheric pressure using the ambient high-pressure cell. Combining the micro focusing with the wide-acceptance-angle objective lens (WAAEL) it will be possible to measure angle resolved hard X-ray photoemission spectroscopy (HAXPES) at BL47XU in SPring-8. In this presentation, we will talk some development of the ambient high-pressure cell and experimental results of Au nanoparticle-dispersed solution.
