“…Future work could include other diatomic and polyatomic molecules, vibrationally resolved results, and studies of double excitation and other interchannel interactions. In related work, there is significant interest in confinement resonances that arise in photoionization of atoms contained in C 60 molecular cages [62]. Strong nondipole effects have been predicted in photoionization calculations on confined atoms [63,64].…”

We describe a theoretical approach to molecular photoionization that includes first-order corrections to the dipole approximation. The theoretical formalism is presented and applied to photoionization of H 2 over the 20-to 180-eV photon energy range. The angle-integrated cross section σ , the electric dipole anisotropy parameter β e , the molecular alignment anisotropy parameter β m , and the first-order nondipole asymmetry parameters γ and δ were calculated within the single-channel, static-exchange approximation. The calculated parameters are compared with previous measurements of σ and β m and the present measurements of β e and γ + 3δ. The dipole and nondipole angular distribution parameters were determined simultaneously using an efficient, multiangle measurement technique. Good overall agreement is observed between the magnitudes and spectral variations of the calculated and measured parameters. The nondipole asymmetries of He 1s and Ne 2p photoelectrons were also measured in the course of this work.

“…The figure has been taken from CSR storage ring. In addition, even more heavy species will become accessible such as (endohedral) fullerene ions which also exhibit strong collective photoionization resonances (Scully et al 2005, Phaneuf et al 2013, and references therein).…”

In the past two decades, the electron-ion merged-beams technique has extensively been exploited at heavy-ion storage rings equipped with electron coolers for spectroscopic studies of highly charged ions as well as for measuring absolute cross sections and rate coefficients for electron-ion recombination and electron-impact ionization of multiply charged atoms ions. Some recent results are highlighted and future perspectives are pointed out, in particular, in view of novel experimental possibilities at the FAIR facility in Darmstadt and at the Cryogenic Storage Ring at the Max-PlanckInstitute for Nuclear Physics in Heidelberg.

“…After submission of this article Phaneuf et al [48] published an experimental and theoretical study of confinement resonances of photoionized Xe encaged in C + 60 . They found unprecedented evidence of redistribution of oscillator strength due to multipath interference of the excited photoelectron.…”

, and the semiconducting BaSi 2 . Here, non-resonant x-ray Raman scattering is used to investigate confinement effects on the shape of the giant resonance in the vicinity of the Ba N IV,V -edge. The distinct momentum transfer dependence of the spectra is analyzed and discussed. The measurements are confronted with calculations of the giant resonance within time-dependent local density approximation in the dipole limit. No modulation of the giant resonance's shape for Ba atoms confined in different local environments was observed, unlike predicted by the calculations. The absence of such shape modulation for complex Ba/Si compounds is discussed providing important implications for further studies of giant resonance phenomena utilizing both theory and experiment.
