| Outline of Final Research Achievements |
We have succeeded in constructing the time-resolved inelastic photoemission system. The temporal resolution of the system has been determined by using two-color two-photon photoemission spectroscopic measurement. The resolution is approximately 2 ps, which is equivalent to the ideal limit determined from the width of the laser pulse.
By using this system, we measured the inelastic photoemission spectra of CO covered Cu(001) surface with the pump probe technique. The spectral feature arising from the frustrated rotation mode of CO molecule, but it was not significantly affected by the picosecond IR laser pulses, unfortunately. We concluded that the picosecond pulses are not sufficient to temporarily excite the CO molecule on the Cu(001) surfaces. In the future, we would improve the laser power and simultaneously search for the suitable sample (substrate) for this technique.
