Static Electric Field in Vacuum
2016This chapter introduces forces between charges at rest, which are not supposed to be inside any media (Coulomb’s law). Concepts such as electric field or electric potential are introduced, as well as its calculus when produced by different charge distributions, including conductive materials. Gauss’ law and its use to calculate electric field caused by

p-wave photodetachment in a static electric field
Physical Review A, 1993Photodetachment from negative ions initially bound in [ital s] states has been studied in a static electric field. A 10-keV ion beam was sent through a region with fields of up to 1.5 kV/cm applied parallel to the beam direction. A pulsed dye-laser beam, perpendicular to the ion beam, photodetached the ions. The relative cross sections were measured by

The properties of static electric fields are examined and the concept of electrostatic potential is introduced. It is shown that Gauss’ law leads, in a straightforward way, to Coulomb’s law. The electrostatic properties of a metallic conductor are studied.

Static Electric and Magnetic Fields
IETE Journal of Education, 1994This article presents a discussion on basic and fundamental concepts of static electric and magnetic fields. Expressions for the field and potential functions and equations satisfied by the flux, potential and field functions are derived. Interesting conclusions are also pointed out.

Double Excitations of Helium in Weak Static Electric Fields
Physical Review Letters, 2006A dramatic electric field dependence has been observed in the fluorescence yield spectrum of the doubly excited states in helium, where a rich phenomenology is encountered below the threshold. Fluorescence yields of certain states can be tuned to zero, while other dipole-forbidden states are significantly enhanced, for fields much weaker than 1 kV/cm ...

Static electric fields in vacuum
2018This chapter begins using Coulomb’s law to derive Maxwell’s electrostatic equations for a vacuum. In doing this, the integral forms of the electrostatic potential Ф and field E are obtained. These results are then used to determine Ф and E for various charge distributions possessing some symmetry: either via Gauss’s law or by directly integrating a ...

Motion of Paramecium in static electric and magnetic fields
Journal of Theoretical Biology, 1970Abstract An elementary quantitative model, based on Jahn's “volume conductor” theory, is described to explain the motion of Paramecium in static electric fields (galvanotaxis). An expression for the orientation sensitivity to electric fields is derived.

Photoionization of Ca in a static electric field
Physical Review A, 2010We present a joint theoretical and experimental investigation for electric-field effects on ground-state photoionization of Ca. For an electric field with its direction along the z axis, the dominant field-free, doubly excited, odd-parity (i.e., 3dnp and/or 3dnf) resonances of the {sup 1,3}L{sub J=1}{sup o} (i.e., {sup 1,3}P{sub J=1}{sup o} and {sup 3 ...

Static electric fields modify the locomotory behaviour of cockroaches
Journal of Experimental Biology, 2011SUMMARYStatic electric fields are found throughout the environment and there is growing interest in how electric fields influence insect behaviour. Here we have analysed the locomotory behaviour of cockroaches (Periplaneta americana) in response to static electric fields at levels equal to and above those found in the natural environment.
