Numerical data and functional relationships in science and technology : new series. Group 1 Elementary particles, nuclei and atoms Vol. 17 Photon and electron interactions with atoms, molecules and ions Subvol. c Interactions of photons and electrons with

Interactions of photons and electrons with atoms, molecules, and ions are fundamental elementary processes in a wide variety of neutral or ionized gases in nature or laboratory. The data on the cross sections or related quantities for those processes are eagerly needed in many fields of application such as astrophysics, atmospheric science, plasma science, radiation physics and chemistry, etc. They are also important in understanding physical or chemical properties of atoms, molecules, and their ions. Volume I/17 provides cross section data and related quantitative information on the interactions of photons and electrons with atoms and molecules (subvols. A and C, resp.), and collisions of electrons with atomic ions (subvol.B). 4 Cross sections for photoabsorption, photoionization, neutral dissociation of molecules K. Kameta, N. Kouchi, Y.
