  • &Lt
  • P&Gt
  • The Recollision Model Has Been Applied To Separate The Probability For Double Ionization Into Contri
  • For A Wavelength Of 780 Am
  • Electron-Impact Excitation Dominates Just Above The Threshold Intensity For Double Ionization
  • Approximate To 1
  • 2 X 10(14) W Cm(-2)
  • With Electron-Impact Ionization Becoming More Important For Higher Intensities
  • For A Wavelength Of 390 Nm
  • The Ratio Between Electron-Impact Ionization And Electron-Impact Excitation Remains Fairly Constant
  • Approximate To 6 X 10(14) W Cm(-2)
