This expression is typically valid for a plasma in which ion thermal velocities are much less than electron thermal velocities. A detailed discussion of the Coulomb logarithm is available in the ''NRL Plasma Formulary'', pages 34–35.

Note that the word parameter is usually used in plasma physics to refer to bulk plasma properties in general: see [[plasma parameters]]. pabbbbbbeeeeebbbebbebbebeuiwhgk,kfeeeeererjhirrjwekddflerke

An alternative definition of this parameter is given by the average numberehfffwr of electrons in a [[plasma (physics)|plasma]] contained within a [[Debye sphere]] (a sphere of radius the [[Debye length]]).

An alternative definition of this parameter is given by the average number of electrons in a [[plasma (physics)|plasma]] contained within a [[Debye sphere]] (a sphere of radius the [[Debye length]]).

This definition of the plasma parameter is more frequently (and appropriately) called the Debye number, and is denoted <math> N_D</math>. In this context, the plasma parameter is defined as
