Electron emission in heavy ion-atom collisions reviews the theoretical and experimental work on the last 30 years on continuous electron emission in energetic ion-atom collisions. Emphasis is placed on the interpretation of ionization mechanisms. These mechanisms are interpreted in terms of the strength of the electronic interaction with the heavy particles. These mechanisms are interpreted in terms of Coulomb centers associated with the projectile and target nuclear fields which strongly interact with the outgoing electron. In particular, the cases of electron emission in one and two centers are analyzed. As examples, electron emission in binary and soft collisions with bare projectiles are treatedas cases for single-projectile and target centers, respectively. General properties of the two-center electron emission are analyzed using electron-capture to the continuum and saddle-point electron emission as specific examples. For dressed projectiles, particular attention is devoted to screening effects, anomalies in the binary-encounter peak production, diffraction effects, and dielectronic processes involving two active electrons. Lastle, a brief overview of multiple ionization processes is presented. The survey concludes with the compilation of experimental studies related to heavy ion impact ionization.
