The book is meant as an introduction into the field and provides some basic theoretical understanding of the atomic processes occurring when a projectile hits another atom. It also furnishes the tools for a mathematical description, however, without going deeper into the technical details, which can be found in the literature given. With this aim, the focus is on reactions, in which onlyNorth-Holland personal library.Ion-atom collisionsCollisions (Nuclear physics)Electronic books.Ion-atom collisions.Collisions (Nuclear physics)539.7/57Eichler Jörg1934-44824MiAaPQMiAaPQMiAaPQBOOK9910458435703321Lectures on ion-atom collisions2242675UNINA
