Statistical Physics of Nanoparticles in the Gas Phase Thermal processes are ubiquitous and an understanding of thermal phenomena is essential for a complete description of the physics of nanoparticles both for the purpose of modeling the dynamics of the particles and for the correct interpretation of experimental data. The second edition of this book follows the logic of first edition with an emphasis on presentation of literature results and to guide the reader through derivations. Several topics have been added to the repertoire notably magnetism a fuller exposition of aggregation and the related area of nucleation theory. Also a new chapter has been added on the transient hot electron phenomenon. The book remains focused on the fundamental properties of nanosystems in the gas phase. Each chapter is enriched with more new exercises and three Appendices provide additional useful material Introduction The relation between classical and quantum statistics Microcanonical temperature Thermal properties of vibrations Rate constants for emission of atoms and electrons Radiation The evaporative ensemble Abundance distributions; large scale features Molecular dynamics and Monte Carlo simulations Thermal excitation of valence electrons Hot Electron Reactions He droplets Phase Transitions A Additional reading B Constants of nature and conversion factors C Mathematical help Index
