Advances in Imaging and Electron Physics

In this volume, the authors extend the calculus of finite differences to Dirac's equation. They obtain solutions for particles with negative mass. In addition, they Obtain solutions for nuclear distances of the order of 10 ^-13 m and less rather than for the usual atomic distances. They report a number of different variations in the eigenvalues of an electron in a Coulomb field, similar to the Lamb shift. In a section of the area of the dx by delta x .
