Klappentext This 1976 book reflects how advancing technology facilitated experimental work on the properties of negative ions in gases. Zusammenfassung This 1976 book is the third edition of a book first published in 1938. After 1950! when the previous edition was published! advancing technology facilitated experimental work on the properties of negative ions in gases. Inclusion of so much fresh material means that less emphasis is placed on some earlier knowledge and techniques. Inhaltsverzeichnis Preface; 1. Introduction - the negative ion of hydrogen (H-); 2. Ground states of complex atomic negative ions - theoretical considerations; 3. The electron affinities of the elements; 4. Atomic negative ions - excited states - autodetachment, general account; 5. Autodetaching states of specific atomic negative ions; 6. Molecular negative ions - grounds states; 7. Excited electronic states of molecular negative ions; 8. Modes of formation of negative ions - formation by radiative processes - radiative attachment and polar photodissociations; 9. Modes of formation of negative ions - formation by three-body collisions of electrons - electron affinity; 10. Formation of negative ions by capture of bound electrons; 11. Detachment of electrons from negative ions - photodetachment, field detachment and detachment by electron impact; 12. Detachment, charge transfer and other reactions between negative ions and neutral systems at low and intermediate energies; 13. Detachment, charge transfer and other reactions involving negative ions- collisions at high impact energies; 14. Recombinations of negative and positive ions - mutual neutralization; 15. Negative ions in electric discharges, planetary and stellar atmospheres, trace analysis and tandem accelerators; References; Author index; Subject index.
