Abstract The nonextensivity in a nonisothermal plasma system with the Coulombian long-range interaction is studied in the framework of Tsallis statistics. We present for first time a mathematical expression of the nonextensive parameter q based on the mathematical theory about the generalized Boltzmann equation and the q–H theorem and the Maxwellian q-velocity distribution. We obtain a new physical explanation for q ≠ 1 related to the nature of nonisothermal configurations in the plasma systems with the Coulombian long-range interaction, which means that Tsallis statistics might be a suitable statistics for the description of a nonequilibrium system with long-range interactions and with a temperature gradient in it.
