Since their founding as independent nations, nuclear issues have been key elements of nationalism and the public sphere in both India and Pakistan. Yet the relationship between nuclear arms and civil society in the region is seldom taken into account in conventional security studies. These original and provocative essays examine the political and ideological components of national drives to possess and test nuclear weapons. Equal coverage for comparable issues in each country frames the volume as a genuine dialogue across this contested boundary.

Atomic Structure Theory Lectures on Atomic Physics


Free Download Atomic Structure Theory: Lectures on Atomic Physics by Walter R. Johnson
English | February 5, 2007 | ISBN: 3540680101 | 324 pages | PDF | 3.13 Mb
Atomic Structure Theory is a textbook for students with a background in quantum mechanics. The text is designed to give hands-on experience with atomic structure calculations. Material covered includes angular momentum methods, the central field Schrödinger and Dirac equations, Hartree-Fock and Dirac-Hartree-Fock equations, multiplet structure, hyperfine structure, the isotope shift, dipole and multipole transitions, basic many-body perturbation theory, configuration interaction, and correlation corrections to matrix elements. Numerical methods for solving the Schrödinger and Dirac eigenvalue problems and the (Dirac)-Hartree-Fock equations are given as well. B-spline basis sets are used to carry out sums arising in higher-order many-body calculations. Illustrative problems are provided, together with solutions. FORTRAN programs implementing the numerical methods in the text are included.

What does Artificial Intelligence mean for our identity? Our fascination with AI stems from the perceived uniqueness of human intelligence. We believe it’s what differentiates us. Fears of AI not only concern how it invades our digital lives, but also the implied threat of an intelligence that displaces us from our position at the centre of the world.

Computational Atomic Physics Electron and Positron Collisions with Atoms and Ions


Free Download Computational Atomic Physics: Electron and Positron Collisions with Atoms and Ions By Klaus Bartschat (auth.), Professor Dr. Klaus Bartschat (eds.)
1996 | 249 Pages | ISBN: 3642646557 | PDF | 9 MB
"Computational Atomic Physics" deals with computational methods for calculating electron (and positron) scattering from atoms and ions, including elastic scattering, excitation, and ionization processes. After an introductory chapter on atomic collision theory, two chapters are devoted to the bound-state wavefunctions. A description of perturbative methods is followed by discussions of the standard non-perturbative close-coupling theory, the R-matrix method, and the recently developed "convergent-close-coupling" approach. The details of calculating accurate Coulomb and Bessel functions are treated as well. Finally, the calculation of scattering amplitudes is discussed and an introduction to the density-matrix theory is given. The book provides a practical application of advanced quantum mechanics. The abstract equations of general scattering theory are reduced to numerically solvable differential and integral equations, and computer codes for the solution are provided. Numerous suggested problems in the text and ten programs on a diskette contribute to a deeper understanding of the field. The diskette The 10 program packages included on a 3 1/2" MS-DOS diskette are written in standard FORTRAN 77 and run on any computer that fulfills the following system requirements: 16MB RAM, MS-DOS 3.30 or higher; 486 DX processor with numerical coprocessor. The FORTRAN 77 source files allow for modification of the programs; therefore a FORTRAN 77 compiler is also needed. Example input and output files are provided for the text cases. * COREPOT core potentials * CIV3 atomic structure * DWBA first order distorted wave program for excitation * DWBIA first order distorted wave program for ionization * CCPA close-coupling for positron-atom scattering * RMATREX R-matrix program for electron-atom scattering * CCC convergent close-coupling * COUL90 Coulomb and Bessel functions

Atomic and Nuclear Clusters Proceedings of the Second International Conference at Santorini, Greece, June 28 – July 2, 1993


Free Download Atomic and Nuclear Clusters: Proceedings of the Second International Conference at Santorini, Greece, June 28 – July 2, 1993 By Professor G. S. Anagnostatos, Professor Dr. W. von Oertzen (eds.)
1995 | 317 Pages | ISBN: 3642796982 | PDF | 20 MB
The subject of clusters – small aggregates of particles – is a topic of primary interest in both atomic and nuclear physics, and also in other fields such as the quark-structures of baryons and cosmology. The interplay between atomic and nuclear physics is a particularly fascinating one because many concepts are common to both fields (quantal effects, shells, geometric structures, collective modes, fission, etc.). These proceedings contain a wealth of papers illustrating the interdisciplinary role of cluster physics. Some of them are reprinted from Zeitschrift für Physik A and D.
