This volume describes the advanced research on the behavior of electrons in ionized atoms and molecules. Readers will learn about relevant techniques used and experimental results for different electron and molecular theories. The information presented in the book is useful for scholars and researchers involved in nuclear and atomic physics programs. Topics covered in the volume include:-Ionization experiments-Kinetic energy studies of photoexcited carbon dichloride and tetrachloride molecules-Selective excision of biomolecules in electron transfer experiments-Particle and antiparticle collisions with rare gases-Multiple scattering in electron Rutherford scattering spectroscopy-Four-body effects in the 6He58 +58Ni scattering-Twin atoms from doubly excited states of the hydrogen molecule
