Synopses & Reviews
This volume aims to provide the fundamental knowledge to appreciate the advantages of the J-matrix method and to encourage its use and further development. The J-matrix method is an algebraic method of quantum scattering with substantial success in atomic and nuclear physics. The accuracy and convergence property of the method compares favourably with other successful scattering calculation methods. Despite its thirty-year long history new applications are being found for the J-matrix method. This book gives a brief account of the recent developments and some selected applications of the method in atomic and nuclear physics. New findings are reported in which experimental results are compared to theoretical calculations. Modifications, improvements and extensions of the method are discussed using the language of the J-matrix. The volume starts with a Foreword by the two co-founders of the method, E.J. Heller and H.A. Yamani and it contains contributions from 24 prominent international researchers.
Synopsis
The J-matrix is an algebraic method of quantum scattering with substantial success in atomic and nuclear physics. The accuracy and convergence property of the method compares favorably with other successful scattering calculation methods. Although introduced thirty years ago, the J-matrix method has witnessed a resurgence of interest in the last few years.
This volume gives a brief account of recent developments and some selected applications of the method in atomic and nuclear physics. It contains an edited collection of new and original contributions of 24 prominent researchers from different parts of the World. The book is compiled of 14 chapters that are grouped into 5 sections. Each chapter is written as an independent article by one or more authors. The volume starts with a Foreword by the two co-founders of the method, E.J. Heller and H.A. Yamani, who are also co-editors of the volume.
