1961 Physics of Fluids IV. 139 Ion oscillations..are obtained using a formalism which is sometimes designated as ‘collisionless’.

1962 W. B. Thompson Introd. Plasma Physics viii. 203 It might be thought that the vast scale of astrophysical phenomena precluded the application of the collisionless theory, but this is by no means clear.

1971 Physics Bull. Aug. 477/3 The scattering technique was used to gain understanding of plasma microturbulence and its role in fusion devices and collisionless shocks in astrophysics.

1983 Jrnl. Geophysical Res. 88 A. 7893/1 We have used a semikinetic model to describe the steady state collisionless flow of H⁺, O⁺ and electrons along diverging geomagnetic field lines in the high-latitude topside ionosphere.
