Adiabatic Theory of Electron Detachment from Negative Ions in Two-Color Laser Field
Get PDFNegative ion detachment in bichromatic laser field is considered within the
adiabatic theory. The latter represents a recent modification of the famous
Keldysh model for multiphoton ionization which makes it quantitatively
reliable. We calculate angular differential detachment rates, partial rates for
particular ATD (Above Threshold Detachment) channels and total detachment rates
for the Hydrogen ion in a bichromatic field with 1:3 frequency ratio and
various phase differences. Reliability of the present, extremely simple
approach is testified by comparison with much more elaborate earlier
calculations.Comment: 22 pages, 6 Postscript figure
