Modified Debye-hückel Electron Shielding and Penetration Factor
نویسنده
چکیده
Screened potential, modified by non standard electron cloud distributions responsible for the shielding effect on fusion of reacting nuclei in astrophysical plasmas, is derived. The case of clouds with depleted tails in space coordinates is discussed. The modified screened potential is obtained both from statistical mechanics arguments based on fluctuations of the inverse of the Debye-Hückel radius and from the solution of a Bernoulli equation used in generalized statistical mechanics. Plots and tables useful in evaluating penetration probability at any energy are provided. Subject headings: Plasmas — nuclear reactions — atomic processes

Dosimetric pitfalls in the application of shielding disk in breast intraoperative electron radiation therapy
Introduction: Intraoperative electron radiotherapy (IOERT) is an IORT technique in which electron beams with different nominal energies are used for irradiation of microscopic residual of tumor bed after surgery. Application of a shielding disk, which is positioned under the target volume, for protecting the normal tissues such as pectoral muscle, lung, and heart is one of the a...
متن کاملDynamic and Debye shielding and antishielding in magnetized, collisionless plasmas.
While shielding in collisional, strongly magnetized (one-dimensional) plasmas obeys the standard Debye result, shielding in collisionless, immobile ion plasmas is far more complex than commonly believed. In some circumstances, the plasma will antishield a positive test charge; i.e., the plasma becomes more positive in the neighborhood of a positive test charge. When shielding does occur, it res...
متن کاملComputational Investigation on Naphthoquinone Derivatives :Nuclear Magnetic Resonance (NMR) and Quantum mechanic
Naphthoquinones are natural aromatic compounds that can be discovered in various plant families. In recent times a diversity of biological activities of these compounds has been reported. In most cases, these pharmacological activities are related to redox and acid-base properties, which can be modulated synthetically by modifying the substituents attached to the 1, 4- naphthoquinone ring, in o...
متن کاملShielding from instantaneously and adiabatically applied potential wells in collisionless plasmas
The response of collisionless plasmas to an applied potential can differ from classic Debye shielding, and when the potential is rapidly applied ~‘‘instantaneous shielding’’!, the shielding can differ from when it is slowly applied ~‘‘adiabatic shielding’’!. Experiments demonstrate that when a test potential well is applied to a one-dimensional pure-electron plasma, instantaneous and adiabatic ...
متن کاملLong Time Behavior of Solutions to Nernst–Planck and Debye–Hückel Drift–Diffusion Systems
We study the convergence rates of solutions to drift-diffusion systems (arising from plasma, semiconductors and electrolytes theories) to their self-similar or steady states. This analysis involves entropytype Lyapunov functionals and logarithmic Sobolev inequalities.
