Publisher Summary This chapter focuses on diabatic states of molecules. Quasi-stationary state representation is proposed as a general definition of the diubutic or collisional electronic states of molecules, diatomic, and polyatomic. The identification of the single configuration diabatic states that seem to be followed by atoms colliding in nature appears to be an important step in understanding atomic collisions. Because an electron taken far away from the residual core sees the screened charge of a neutral system rather than an attractive Coulomb field, there are no Rydberg states for negative systems.read more

Theory of Dissociative Attachment
TL;DR: In this paper, a comprehensive theoretical treatment of the dissociative attachment (DA) of electrons to diatomic molecules is given, going from general formalism to explicit cross-section formulas and comparison with experimental results.
