Spectroscopy enables the precise study of astronomical objects and phenomena. Bridging
the gap between physics and astronomy, this is the first integrated graduate-level textbook …

The van der Waals coefficients, C 6, C 8, and C 10 for the alkali-metal (Li, Na, K, and Rb)
and alkaline-earth-metal (Be, Mg, Ca, and Sr) atoms are estimated by a combination of ab …

The merged-beams technique is powerful for the experimental study of certain classes of
atomic and molecular processes that cannot be as readily or accurately addressed by other …

Fully relativistic distorted-wave theory has been applied to study the electron-impact
excitation of the ns 1/2-np 1/2 and ns 1/2-np 3/2 resonance transitions of singly charged …

High-and low-resolution International Ultraviolet Explorer (IUE) spectra of V838 Her in the
early outburst stages exhibit a strong absorption feature shortward of λ3130. We discuss the …

A relativistic coupled-cluster theory is implemented to study electron impact excitations of
atomic species. As a test case, the electron impact excitations of the 3 s 2 S 1∕ 2–3 p 2 P …

A scaling method applied to plane-wave Born cross sections for electron-impact excitation of
neutral atoms is modified and applied to Coulomb Born cross sections for excitations of …

A merged-beams electron-energy-loss technique is described, by which absolute cross
sections can be measured for near-threshold electron-impact excitation of multipy charged …

Recent advances in the elucidation of electron-ion scattering phenomena is reviewed, with
particular emphasis on the new generation of experiments where scattered electrons are …

First measurements of absolute total cross sections for electron-impact excitation of an
intercombination transition to a nonradiating state of an ion are reported. The cross sections …
