midpoints between neighboring atoms, and the centers of the hexagonal cells show zero electric field in agreement with previously reported works7,9. Using the projected electric field, we computed the projected potential by integrating the field (Fig.2b) and the projected charge density using Gauss...
IT has recently been suggested by Bondi and Ly ttleton1,2that the magnitudes of the electric charges on the proton and electron may differ by a little more than one part in 1018, in which case electrostatic forces would cause the universe to expand. In fact, Piccard and Kessler3attempted ...
The critical nuclear charge Zc required for a heliumlike atom to have at least one bound state was recently determined with high accuracy from variational calculations. Analysis of the wave functions further suggested that the bound state changes smoothly into a shape resonance as Z crosses the ...

The nonresonant, multiphoton ionization of many-electron atoms is explained theoretically within the Thomas-Fermi model with the inclusion of an electromagnetic field. Numerical results are presented for the charge state and induced dipole moment versus the strength of the applied electric field, which...
1 Momentum-Dependent Charge Transfer Excitations in Sr2CuO2Cl2 –Angle Resolved Electron Energy Loss Spectroscopy Electron-hole pair excitations in the insulating cuprates Sr_2CuO_2Cl_2 Sr_2CuO_2Cl_2 were investigated by angle-resolved electron energy loss spectroscopy. The optically allowed and op...

In their experiment, Ne atoms were exposed to 250 as xuv pump pulse with a central energy of 90 eV and a time-delayed 750 nm laser field with intensityI0=7×1013W/cm2.Fig. 10(a) shows the level structures and transitions relevant to this experiment. A few fractions of the Ne+ions ...
The concept of an indivisible amount of electric charge was theorized to explain the chemical properties of atoms, beginning in 1838 by British natural philosopher Richard Laming; the name electron was introduced for this charge in 1894 by Irish physicist George Johnstone Stoney. The electron was id...
