External Electric FieldHeavy AtomWe consider the differential and partially integrated cross sections for bremsstrahlung from high-energy electrons in an atomic field, with this field taken into account exactly. We use the semiclassical electron Green function and wavefunctions in an external electric ...
The nuclear magnetic screening constant of a hydrogen atom in a uniform electric field is calculated, neglecting any effect of electron spin. The screening is found to be reduced by the electric field for all directions of the applied magnetic field, the reduction being greatest if the two ...
An electric fieldformed at the interface whose strength was 1.32×109Vm−1(Fig. 6.31B). Under illumination, the photogenerated charge carriers migrated according to the S-scheme mechanism. When O atom was introduced, thework functionof g-C3N4decreased from 4.3 to 3.6eV. In other words, the...
In the presence of a stationary electric field of the magnitude up to 105 V/m, carbon chains became oriented along the field lines during the deposition on a solid substrate. Figure 1 (a) The scheme of the experimental setup used for the controlled deposition of carbon chains stabilised with...
The multi-step laser excitation schemes used in this work on the indium atom. Field ionization was used following the two laser steps to a Rydberg state. The lifetime of the intermediate5s25d2D5/2,5s25d2D3/2states is 7.0(4) ns52. Figure created using Ref.44. ...
In the asymptotic region the electric field of an incoming wave is proportional to the spatial components of the gauge field. Therefore, a1,aP describe a beam with electric field in the plane of incidence (TM mode or p-polarized wave). On the other hand, the components aT give an electric...

The interaction energy, U, of an electric field, E, with the dipole, D, is equal to (6.9)U=−D·E Assuming an electric field of 1 V/cm and a dipole moment of about 3000 Debye, the interaction energy of a tubulin dimer can be calculated using the following procedure: (6.10)E=1...
