Abstract

Pump and probe experiments using storage ring free electron laser (SRFEL) and synchrotron radiation (SR) pulses have been tried to perform for the last decade, because the natural synchronization of the SRFEL pulse with the SR pulse makes it easier to do such experiments. Recently, we have successfully carried out the two-photon double-resonant excitation on Xe atoms, utilizing a SR pulse as a pump and an FEL pulse as a probe light. Here, we report the recent experimental results of the investigation for excited states of Xe dimers as well as Xe atoms. The results on the pressure-dependent measurements that were applied to the same system, strongly suggest the formation of Xe dimers in the intermediate states prepared by the primary pump processes.
