Paperback. Condición: New. Print on Demand. This book contributes to the study of elastic scattering of electrons by hydrogen atoms (a topic of great importance to astrophysics and upper atmospheric research) offering a variational method for calculating cross sections using Schwinger's variational expression for the direct elas…tic scattered amplitude. In particular, it applies the method to hydrogen atoms in the energy range 0-10 volts, which is a range currently lacking in experimental data. The methods employed in this book resolve the issue of evaluating the integrals inherent in Schwinger's variational method (which had previously made such calculations difficult) by using Born trial fields. The results of the calculations provide valuable insights into the contributions of the excited states and the continuum to the elastic scattering, and reveal the vital roles played by these factors in the polarization of the charge distribution. This book demonstrates the importance of properly accounting for the elastic effects of the atom's excited states and continuum, particularly in the absence of experimental data in this energy range. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
