The time-energy mapping of the photoionization integral cross section and laboratory-frame photoelectron angular distribution is used to study photoionization stereodynamics of a diatomic molecule. The general theoretical formalism [Y. Suzuki and T. Suzuki, Mol. Phys., 2007, 105, 1675] is simplified for application to a diatomic molecule, and a high-resolution photoelectron imaging apparatus is...

We use intense femtosecond laser pulses to multiply ionize and directly image the structures of N(2)Ar, O(2)Ar, and O(2)Xe dimers by coincidently measuring the momenta of the fragment ions. All these dimers are found to have an equilibrium T-shaped structure in which the bond of the diatomic molecule is perpendicular to the dimer axis. The equilibrium distance between the rare-gas atom and the ...

Direct or Eley-Rideal reactions between energetic N^{+} and O^{+} projectiles and O atoms, adsorbed onto Pt and Pd surfaces, are studied experimentally at incidence energies between 20 and 200 eV. The exit energies of the diatomic molecular products NO and O_{2} depend linearly on the incidence energy of the corresponding projectiles. A reaction mechanism is proposed, where the incident project...

The absorption and fluorescence spectra of a model diatomic molecule with a charge-transfer electronic transition are simulated. The effect of confining the solvent in which the diatomic molecule is dissolved is examined by comparing results for solutions contained within hydrophobic spherical cavities of varying size ~radii of 10–20 Å!. The effect of solvent polarity is also considered by comp...

Analytical and numerical results are presented for the intersection of electronic energies of the same space symmetry for electrons in the field of two Coulomb centers in D-dimensions. We discuss why such crossings are allowed and may be less ‘‘exceptional’’ than one could think because even for a diatomic molecule there is more than one parameter in the electronic Hamiltonian. For a one electr...

New method for dissociation of diatomic molecule based on nonperiodic excitation generated by energy-feedback control mechanism is proposed. The energyfeedback control uses frequency-energy (FE) relation of the natural oscillations to fulfill the resonance conditions at any time of excitation. Efficiency of the proposed method is demonstrated by the problem of dissociation of hydrogen fluoride ...

The gas temperature in non-equilibrium plasmas is often obtained from the plasma-induced emission by measuring the rotational temperature of a diatomic molecule in its excited state. This is motivated by both tradition and the availability of low budget spectrometers. However, non-thermal plasmas do not automatically guarantee that the rotational distribution in the monitored vibrational level ...

We show that light scalars can form quasibound states around binaries. In the nonrelativistic regime, these are formally described by quantum-mechanical Schr\"odinger equation for a one-electron heteronuclear diatomic molecule. performed extensive numerical simulations of scalar fields black hole binaries, showing structure condenses binary---we dub ``gravitational molecules.'' further well per...
