摘要：

Valence photoionization of N-2 has been performed with high-brilliance vacuum ultraviolet radiation at h nu=38.5 +/- 0.2 eV from the free-electron laser at Hamburg (FLASH). As a function of fluence, saturation of photoionization occurs due to the depletion of the ground-state molecular target within each femtosecond radiation pulse. With increasing fluence, the vibrational envelope of the valence photoionization spectral distribution experiences radiation-field-induced changes.
