“…I have not attempted a complete literature search, but note that the research project must have been topical at the time as the inverse third power asymptotic behaviour in Eq. (3.8) was announced a year later by Montgomery, Joyce and Sugihara, 32 in a paper that has been cited 58 times. In fact the problem is even more topical today with the rise of interest in dusty plasmas-for instance the paper by Ishihara and Vladimirov 33 on the wake potential of a dust grain in a plasma with ion flow has been cited more than 80 times.…”

The screened field (forward field and wake) of a test particle moving at constant velocity through an unmagnetized collisionless plasma is calculated analytically and numerically. This paper is based on unpublished material from my MSc thesis, supervised by the late Dr K. C. Hines.Comment: 27 pp, 14 fig Publ "In Celeb Of KC Hines," www.worldscibooks.com/physics/7604.html. Based on Chs 2 & 3 of "Particle-field interactions in a plasma," RL Dewar, MSc Thesis, U Melbourne '67. v2: $\sin\psi$ and $\cos\psi$ interchanged after Eq. (4.1); v3: typos corrected pp 3, 4, 5, 19, in partic. repl. $q$ by $q/\epsilon_0$ & putting hat on k in arg. of \Phi in Eq.(2.5). See also arXiv 1107.520

“…MONTGOMERY et al (1968) have shown for an electron plasma that for a moving test particle, the far field is not exponentially decreasing as in Debye screening, but rather exhibits a'quadrupole field in lowest significant order.…”

“…Far field wake potential decays as the inverse cube of the distance between the origin of the test charge and the location of the observer. It is interesting to note that for far field, the effective potential of a moving "test charge" in an isotropic collision-less classical plasma also falls off as the inverse cube of the distance of the observer from the test charge [31]. The effect of far field wake potential is very small on the binding energy of atom.…”

Precise energy eigenvalues of hydrogen-like ion moving in quantum plasmas

The analytic form of the electrostatic potential felt by a slowly moving test charge in quantum plasma is being derived. It has been shown that the potential composed of two parts: Debye-Huckel screening term and near-field wake potential which depends on the velocity of the test charge and the number density of the plasma electrons. Rayleigh-Ritz variational calculation has been done to estimate precise energy eigenvalues of hydrogen-like ion under such plasma environment. A detailed analysis shows that the energy levels are gradually moves to the continuum with increasing plasma electron density while level crossing phenomenon have been observed with the variation of ion velocity.
