The angular distribution of ion flux around an ionospheric satellite
(Elsevier, 1973-03)
Ion measurements from the Explorer 31 satellite were used to determine the angular distribution of ions around the satellite. The ion distributions were compared with the electron distributions measured on the same satellite. ...
An investigation of nonlinear xenon oscillation by method of averaging
(Elsevier, 1973-12)
A nonlinear analysis of xenon-temperature controlled nuclear reactor dynamics is presented. The set of equations in question belongs to a general class of rate equations with quadratic nonlinearities. Boundedness of the ...
The effect of temperature perturbations on ion-acoustic and drift waves in a weakly collisional plasma
(IOP Publishing Ltd, 1973-07-01)
The influence of temperature perturbations on the propagation and stability of low frequency waves in a weakly collisional plasma is analyzed. Temperature oscillations in general reduce the stability of ion acoustic waves. ...
A new class of switching materials
(The American Institute of Physics, 1973-01)
By combining several volume percent of conducting particles in a semicrystalline matrix, a highly temperature‐dependent resistivity is obtained. The resistivity changes by several orders of magnitude in a small temperature ...
The Reaction pp ⇒ p + Xpp⇒p+X at 405 GeV/c.
(The American Institute of Physics, 1973-05-01)
Preliminary results on the reaction pp ⇒ p + Xpp⇒p+X from an exposure of the NAL 30 inch liquid hydrogen bubble chamber are presented. Single particle inclusive distributions are discussed and compared with corresponding ...
ESR studies of the triplet state of [n.n] paracyclophanes
(The American Institute of Physics, 1973-01-15)
ESR experiments were performed on the triplet state of randomly oriented paracyclophanes in a variety of rigid glasses at temperatures ranging from 103 to 15°K. Spectra were recorded for [2.2]; [3.3]; (4,7,12,15)‐tetramethyl ...
Molecular motions and [lambda] phase transition: Raman and far-ir studies of neat and isotopic mixed hexamethylbenzene crystal
(Elsevier, 1973)
Raman and far-IR studies of hexamethylbenzene (HMB) low temperature crystalline phases (neat and isotopic mixed) are presented. The Raman phonon spectrum changes drastically during the [lambda]-phase transition. Site ...
A comparison of projection operator formalisms for the study of self-diffusion
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1973-11)
The utility of projection operator formalisms for describing the dynamics of many-body systems is studied, and the compatibility of these formalisms with certain approximation schemes is evaluated in the light of known ...
Duality and Regge absorption models
(Elsevier, 1973-07-16)
Pion-nucleon charge-exchange FESRs show that the best current Regge absorption models are not dual. Their strong disagreement with the FESRs is surprising, in view of the well-known correspondence between absorptive zeroes ...
Vibrational relaxation times in some hydrocarbons in the range 300–900°K
(The American Institute of Physics, 1973-12-15)
Vibrational relaxation times were determined in methane, ethylene, acetylene, and cyclopropane in the temperature range 300–900°K. The experiments were performed by measuring the absorption and dispersion of ultrasonic ...
