Vibrational excitation of cyclopropane by electron impact: An experimental test of the discrete-momentum-representation theory with density-functional-theory approximation of polarization and correlation

Čurík, R. ; Čársky, P. ; Allan, Michael

In: Physical Review A - Atomic, Molecular and Optical Physics, 2012, vol. 86, no. 6, p. 062709

The discrete-momentum-representation theory with short-range correlation and polarization approximated by local-density-functional theory has been augmented by connecting the short-range potential to an asymptotic polarization tensor. The capacity of this theory to correctly describe the coupling of a free electron with nuclear motion is tested by a detailed comparison of calculated and measured...

Testing spatial noncommutativity via magnetic hyperfine structure induced by fractional angular momentum of Rydberg system

Zhang, Jian-Zu ; Liu, Hong-Ping ; Cao, Wei ; Gao, Ke-Lin

In: EPL - Europhysics Letters, 2012, vol. 98, no. 4, p. 40002

An approach to solve the critical problem of testing quantum effects of spatial noncommutativity is proposed. Magnetic hyperfine structures in a Rydberg system induced by fractional angular momentum originated from spatial noncommutativity are discussed. The orders of the corresponding magnetic hyperfine splitting of the spectrum ~10−7–10− 8 eV lie within the limits of accuracy of current...

Measurement of the elastic and v = 0 → 1 differential electron–N₂ cross sections over a wide angular range

Allan, Michael

In: Journal of Physics B: Atomic, Molecular and Optical Physics, 2005, vol. 38, no. 20, p. 3655–3672

Absolute differential elastic and vibrational excitation cross sections have been measured for N₂ in the scattering angle ranges starting between 0° and 20° and extending to 180°, at energies between 0.8 and 5 eV. The results agree with many previous measurements, in particular for angles around 90°, but discrepancies were found in some cases for angles close to 0° and 180°. Integral and...
