Case Studies in Atomic Collision Physics II focuses on studies on the role of atomic collision processes in astrophysical plasmas, including ionic recombination, electron transport, and position scattering. The book first discusses three-body recombination of positive and negative ions, as well as introduction to ionic recombination, calculation of the recombination coefficient, ions recombining in their parent gas, and three-body recombination at moderate and high gas-densities. The manuscript also takes a look at precision measurements of electron transport coefficients and differential cross sections in electron impact ionization. The publication examines the interpretation of spectral intensities from laboratory and astrophysical plasmas, atomic processes in astrophysical plasmas, and polarized orbital approximations. Discussions focus on collision rate experiments, line spectrum, collisional excitation and ionization, polarized target wave function, and application to positron scattering and annihilation. The text also ponders on cross sections and electron affinities and the role of metastable particles in collision processes. The selection is a valuable source of data for physicists and readers interested in atomic collision.
