Adiabatic Theory of Electron Detachment from Negative Ions in Two-Color Laser Field
Negative 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 [L. V. Keldysh, Zh. Eksp. Teor. Fiz. 47, 1945 (1964) [Sov. Phys.-JETP 20, 1307 (1965)]] which makes it quantitatively reliable. We calculate angular differential detachment rates, partial rates for partic...
متن کاملec 1 99 7 Electron detachment from negative ions in bichromatic laser field
Negative ion detachment in two-colour laser field is considered within the recent modification of Keldysh model which makes it quantitatively reliable. The general approach is illustrated by calculation of angular differential detachment rates, partial rates for particular ATD (Above Threshold Detachment) channels and total detachment rates for H − ion in bichromatic field with 1:2 frequency ra...
متن کاملTwo-electron photodetachment of negative ions in a strong laser field.
We study the photodetachment of H-, F-, and Br- in a short laser pulse of 800 nm wavelength and 6 x 10(14) W/cm2 peak intensity. Photoelectron spectra, recorded with the use of an imaging technique, reveal a substantial contribution from the sequential process of double detachment of halogen negative ions. The saturation effect is shown to play a crucial role in this process. The role of the al...
متن کاملTwo-photon detachment of electrons from halogen negative ions
Absolute two-photon detachment cross sections and photoelectron angular distribution are calculated for halogen negative ions within lowest-order perturbation theory. The Dyson equation method is used to obtain the outer np ground-state wave functions with proper asymptotic behavior P (r) ∝ exp(−κr), corresponding to correct (experimental) binding energies Eb = h̄ κ/2m. The latter is crucial for...
متن کاملMultiphoton detachment from negative ions: new theory vs experiment
In this paper we compare the results of our adiabatic theory (Gribakin and Kuchiev, Phys. Rev. A, submitted for publication) with other theoretical and experimental results, mostly for halogen negative ions. The theory is based on the Keldysh approach. It shows that the multiphoton detachment rates and the corresponding n-photon detachment cross sections depend only on the asymptotic parameters...
