Generalized Oscillator Strengths for the 61S0→61P1 Transition in Mercury
TLDR
In this paper, the generalized oscillator strength for the 61S0→61P1 transition in mercury has been determined at 300, 400, and 500 eV electron kinetic energy, which is in very good agreement with the optical oscillators strength.Abstract:
The generalized oscillator strengths for the 61S0→61P1 transition in mercury have been determined at 300‐, 400‐, and 500‐eV electron kinetic energy. Extrapolation to zero momentum change gives f0 = 1.11 ± 0.10. This result is in very good agreement with the optical oscillator strength, f0 = 1.18 ± 0.07, which was determined by Lurio using the zero‐field level crossing method.read more

Inelastic Collisions of Fast Charged Particles with Atoms and Molecules-The Bethe Theory Revisited
TL;DR: In this article, the Bethe theory has been updated with a number of new developments which need to be included in that body of material, such as the ${z}^{3}$ effect and the stopping power for particles at extreme relativistic energies.

Power Series Representation of Generalized Oscillator Strengths
TL;DR: In this article, the singularities of the function for complex values of K are used to transform the series into one which converges for all physically attainable values of k. The transformation depends on the ionization potential and the excitation energy, which can be determined experimentally.
