Erratum: Electron rescattering in strong-field photodetachment ofF−[Phys. Rev. A91, 031404(R) (2015)]

Abstract

PACS numbers: 32.80.Gc 31.15.VSeveral omissions in our recent discussion on strong-field photodetachment [1] have been brought to our attention since the work was published. Calculations solving the time-dependent Schrödinger equation (TDSE) for electron rescattering from F − have been carried out previously using the single active electron approximation [2,3]. The ejected-electron distributions presented in [2,3] show clear evidence for the importance of electron rescattering in strong-field photodetachment, and agree well with calculations based on the strong-field approximation.Our ejected-electron spectra, presented in [1], show the same general features as in [2,3]. However, our calculations are based on the solution of the TDSE for a full, 10-electron system, demonstrating the high quality of the final wavefunction obtained using a fully ab initio approach. The capability to describe all electrons also allows us to assess the importance of electron correlations in the multiphoton ionization process, thus going beyond the results previously reported in the literature.As a consequence of our oversight of [2, 3], we misrepresented the results presented in [4] where the rescattering process was found but not shown explicitly [5].Finally, we point out that early studies of the use of the strong field approximation for electron rescattering were previously presented in [6,7]. More recently, angle resolved spectra have been measured experimentally for above threshold detachment of Br − , with a strong-field approximation model providing almost indistinguishable theoretical results [8].

“…Since m = 0 electron states give a dominant contribution to the detachment signal, this error affected the interference patterns of the photoelectron momentum and energy distributions presented in Refs. [1,3]. At the same time, the error in the total detachment probabilities was small.…”

“…1(c) of Ref. [1]. (Of course, neither KTA calculation can reproduce the high-momentum rings, which are due to rescattering.)…”

“…The left column shows the results of the KTA calculation without the phase factor, and the right column shows the KTA results with the correct phase factor. The numerical RMT simulations [1] are displayed in the middle column for comparison. (1) is evaluated for the complex vector p μ , the corresponding polar angle is determined by…”

“…[1] we used R-matrix theory with time dependence (RMT) to study strong-field dynamics of F − in near-infrared linearly polarized laser pulses. We compared the photoelectron spectra with the results of the Keldysh-type approach (KTA) calculation for short pulses [2,3], which enabled us to identify features due to electron rescattering.…”

“…A calculation similar to that of Ref. [1] was also used to identify the effect of electron rescattering in short-pulse multiphoton detachment from F − computed using the R matrix with time dependence (RMT) method [5]. Subsequently, an error in the KTA calculations was uncovered [6].…”
