“…are normally rather large (up to several hundred Bohr radii), which leads to small differences of the slopes of the electronic terms (8). On the other hand, the long-range interactions in * + A B collision systems combined with the huge outer electron orbital sizes result in significant magnitudes of the transition matrix elements (10). Thus, the nonadiabatic regions may spread out to ranges of up to tens of atomic units with the boundaries of R 1 and…”

“…Of particular interest is to study the electron-transfer processes involving highly polar molecules and Rydberg atoms as those are vivid examples of the interaction between two atomic-molecular systems of large sizes. The theoretical description of collisional dynamics of such processes should be carried out by taking into account specific properties of Rydberg atoms [9,10] and multiple curve-crossing effects [11] in nonadiabatic transitions between ionic and covalent electronic terms of a quasimolecule formed during a collision of particles.…”

“…However, these expressions are valid when the resulting anion is a valence bound one with substantial binding energy (e.g., -SF 6 ) and the principal quantum number is high enough (typically > n 25). Unfortunately, the approach [42] cannot be used to treat collisions involving highly polar molecules with small electron affinities as one cannot neglect the interaction of the perturbing particle with the ionic core of Rydberg atom so that the quasifree electron approximation is not justified (see [10,65]).…”

The results of theoretical studies of the resonant quenching and ion-pair formation processes induced by collisions of Rydberg atoms with highly polar molecules possessing small electron affinities are reported. We elaborate an approach for describing collisional dynamics of both processes and demonstrate the predominant role of resonant quenching channel of reaction for the destruction of Rydberg states by electron-attaching molecules. The approach is based on the solution of the coupled differential equations for the transition amplitudes between the ionic and Rydberg covalent terms of a quasimolecule formed during a collision of particles. It takes into account the possibility of the dipole-bound anion decay in the Coulomb field of the positive ionic core and generalizes previous models of charge-transfer processes involving Rydberg atoms to the cases, when the multistate Landau-Zener approaches become inapplicable. Our calculations for ( ) nl Rb atom perturbed by C H SO 2 4 3 , CH CHCN 2 , CH NO 3 2 , CH CN 3 , C H O 3 2 3 , and C H O 3 4 3molecules show that the curves representing the dependence of the resonant quenching cross sections on the principal quantum number n are bell-shaped with the positions of maxima being shifted towards lower values of n and the peak values, ( ) s max q , several times higher than those for the ion-pair formation, ( ) s max i . We obtain a simple power relation between the energy of electron affinity of a molecule and the position of maximum in n-dependence of the resonant quenching cross section. It can be used as an additional means for determining small binding energies of dipole-bound anions from the experimental data on resonant quenching of Rydberg states by highly polar molecules.

In the literature of Low-Energy Nuclear Reactions (LENR), particle tracks in photographic emulsions (and other materials) associated with certain electrical discharges have been reported. Some Russian and French researchers have considered these particles to be magnetic monopoles. These tracks correspond directly to tracks created with a simple uniform exposure to photons without an electrical discharge source. This simpler method of producing tracks supports a comprehensive exploration of particle track properties. Out of 750 exposures with this method, elliptical particle tracks were detected, 22 of which were compared to Bohr-Sommerfeld electron orbits. Ellipses fitted to the tracks were found to have quantized semi-major axis sizes with ratios of n 2 /α 2 to corresponding Bohr-Sommerfeld hydrogen ellipses. This prompts inquiry relevant to magnetic monopoles due to the n 2 /α 2 force difference between magnetic charge and electric charge using the Schwinger quantization condition. A model using analogy with the electron indicates that the elliptical tracks could be created by a bound magnetically charged particle with mass mm = 1.45 × 10 −3 eV/c 2 , yet with superluminal velocities. Using a modified extended relativity model, mm becomes the relativistic mass of a superluminal electron, with m0 = 5.11 × 10 5 eV/c 2 , the fine structure constant becomes a mass ratio and charge quantization is the result of two states of the electron.

“…The central force involved is active over a range from ∼ 2.54×10 −5 m to 4.07×10 −3 m. The strong force, weak force and gravity are negligible at these distances. Electrostatic central force is within the range with the largest known electron orbits of order n ∼ 1000 in Rydberg atoms with radius 10 −4 m [17], but is ruled out by the inability of tracks of known charged particles to register smooth curvature in emulsions. The remaining possibility is magnetostatic central force, i.e.…”

This prompts inquiry relevant to magnetic monopoles due to the n2/α2 force difference between magnetic charge and electric charge using the Schwinger quantization condition.
