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 and the Born approximations, making use of a formula for the asymptotic expansion of the ...

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...
For pt. I see abstr. A66822 of 1970. Heisenberg's form of the correspondence principle is used to study the excitation of hydrogen atoms and hydrogen-like ions by incident electrons or by incident ions. Using this correspondence principle and a generalization it is shown that there are at le...
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 ...
Derivation of expressions for the excitation cross section in the dipole approximation of the semiclassical impact parameter and the Born approximations, making use of a formula given by Menzel (1968, 1969) for the asymptotic expansion of the oscillator strength of the hydrogen-like atoms. When only...
Diffusionlike aspects of multiphoton absorption in electrically polarized highly excited hydrogen atoms We have observed microwave transitions of overall order up to 16 in hydrogen atoms initially in n=60 lowest-energy Stark states. Increases in n as large as... JE Bayfield,LA Pinnaduwage - 《Phys...

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...
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...
