Expressions for the excitation cross section of the highly excited states of the hydrogenlike atoms by fast charged particles have been derived in the dipole approximation of the semiclassical impact parameter

The deexcitation of exotic hydrogen atoms in highly excited states in collisions with hydrogen molecules has been studied using the classical-trajectory Monte Carlo method. The Coulomb transitions with large change of principal quantum number n have been found to be the dominant collisional deexcitation...
Long-lived excited states of hydrogen, carbon and nitrogen atoms (H**, C** and N**) produced by the electron bombardment of CH3CN in the energy range from 20 to 100 eV were detected as H+, C+ and N+ ions as a result of collisions with H2O. The appearance potential of H+ was ...
Excitons, analogous to atoms in solid-state materials, consist of a positively-charged hole and a negatively-charged electron, giving rise to energy levels like those of hydrogen atoms, which can exhibit Rydberg states, as well24. Unlike atoms, however, excitons are embedded in solid-state hosts...
Energies of excited s-like donor (P, As, Li) states in silicon are determined from two-electron transition spectra. For the 2 s-state of phosphorus and arsenic the effective-mass-theory is in error by ≈2 meV and becomes successively better for the higher excited states, but agrees ...
We presented a setup created on the RADEX neutron channel at the Institute for Nuclear Research of the Russian Academy of Sciences to study the properties of highly excited states of light nuclei. The first experiment was carried out on the setup to determine the cluster structure of highly exci...
The characteristic timescale of proton transfer along the hydrogen bond from H2O•+ to the H2O molecule in liquid water is 30–200 fs [9,15]. In addition, dissociation of the excited state of water (H2O*) leads to •OH and H-atom (G = 0.5 mol J−1) via molecula...
In this work an analysis of the highly vibrationally excited states of thiophosgene (SCCl 2 ) is made in order to gain insights into some of the experimental observations and spectral features. The states analysed here lie in a spectrally complex region where strong mode mixings are expected due...
