| Outline of Final Research Achievements |
The purpose of the present study is (i) to establish the new experimental method using combination of synchrotron radiation and laser light in order to analyze the ground (occupied) states and excited (unoccupied) states of the samples under the same conditions, (ii) to apply this method to analyze the electronic states of molecular condensed matters (amino-acid and nitrite salt), showing the usefulness of the present method, and (iii) to investigate the relaxation dynamics of the excited states of these molecular condensed matters, showing the future prospect of the present method. The experiments were carried out at beamline BL13 of Saga-University Synchrotron Light Application Center, Saga, Japan. Using a soft x-ray and photoelectron spectroscopy system, core absorption and resonant photoemission data were successfully obtained on cysteine and sodium nitrite thin films. The results show clearly the occupied and unoccupied electronic states of these matters.
