“…The agreement between calculation and experiment is excellent over the whole range of energy covered by the experiment. The overall agreement with the results by Zhou et al [7] is also very good. The main difference is in the region just above the first photodetachment threshold where our values for the total cross section, experimental and theoretical, increase monotonically, without the narrow peak due to a slightly larger contribution from the C(1s 2 2s 2 2p 2 3 P ) + e − (ℓ = 0) channel in the calculations of [7].…”

“…Our current capabilities using this frozen core approximation, as opposed to, for example, the more rigorous Rmatrix approach [16,17] used by more established practitioners in the photodetachment field (e.g. [18]), is appropriate in this Ce − case for several reasons. The most practical issue is the size of the final state calculation.…”

“…III). Since we are comparing our results with experimental LPES measurements [10] where the incident photon energy is fixed, rather than the variable photon energy of the laser photodetachment threshold (LPT) method, concerns regarding the possible narrow resonance features present in calculations over a wide range of photon energies [18] are also less immediate. Finally, we consider that our stated goal of these calculations is to determine the dominant photodetachment channels and identify them with the features of the experimental [10] kinetic energy spectrum.…”

The electron affinity of cerium is determined from relativistic configuration interaction photodetachment calculations through a reinterpretation of available experimental data ͓V. T. Davis and J. S. Thompson, Phys. Rev. Lett. 88, 073003 ͑2002͔͒. This analysis yields a 4f5d 2 6s 2 4 H 7/2 Ce − ground state ͑a 5d attachment relative to the 4f5d6s 2 1 G 4 neutral Ce ground state͒ with binding energy of 0.660 eV as well as 18 other bound states of the same configuration. The lowest-lying state of seven bound states of the opposite parity ͑6p attachments͒ is 4f5d6s 2 6p 2 H 9/2 , which is bound by 0.300 eV.

The recent development of experimental photoionization cross sections of atomic ions has been reviewed. Owing to the construction of intense undulator-based photon sources it has been possible during the last ten years to perform a large number of absolute cross-section measurements using the merged-beam method. Photoionization cross sections provide a critical test of theoretical calculations, with implications for the modelling of astrophysical and laboratory plasmas for which fundamental data of this kind are required.
