Multiphoton ionization processes in He using 41.8 eV soft X-ray photons are observed. Intense soft X-ray generated by phase-matched high-order harmonics enables the investigation of these nonlinear optical processes. The harmonics were introduced to a conventional time-of-flight (TOF) mass spectrometer to observe ion signals. The TOF spectra and photoelectron spectra of He are measured.
