We calculate the photoionization cross-section of a molecular endohedral. We limit ourselves to two-atomic molecules. The consideration is much more complex than for atomic endohedrals because the system even for almost spherical fullerenes has only

We experimentally study $2p$ photoionization of neon dimers (${\mathrm{Ne}}_{2}$) at a photon energy of $h\ensuremath{\nu}=36.56\text{ }\text{ }\mathrm{eV}$. By postselection of ionization events which lead to a dissociation into ${\mathrm{Ne}}^{+}+\

We report on fully differential cross sections for double ionization of H2 by a single circularly polarized photon of 160 eV energy. For an unequal sharing of the energy between the two electrons and a particular geometry where the influence of elect

Although valence electrons are clearly delocalized in molecular bonding frameworks, chemists and physicists have long debated the question of whether the core vacancy created in a homonuclear diatomic molecule by absorption of a single x-ray photon i

Energy spectra of electrons ejected in electron impact on CO molecules have been measured for the incident electron energy 1400 eV. The aim was to study the interatomic Auger transitions resulted from the filling in the O K-shell hole by a C K-shell

A new version of the relaxed core Hartree–Fock approximation with a fractional charge of the molecular ion state is applied for calculations of molecular photoionization processes. The set of continuous spectrum wave functions obtained by that meth

The core-level photoelectron spectra of N2 molecules are observed at high energy resolution, resolving the 1σg and 1σu components as well as the vibrational components in the extended energy region from the threshold up to 1 keV. The σg/σu cross
