Caption: Figure 2: Distribution of the emission's current densities in the penetration channel during excitation of a non-self-sustaining discharge: [j.sub.t0] is the density of the thermionic current; [j.sub.t] is the current density, accounting for the Schottky effect.
(1.1) has been subject of many studies in the literature such as the theory of stellar structure, thermionic currents and isothermal gas spheres [11].
Generalized Lane-Emden equations arise in the modeling of several phenomena in physics and astrophysics such as the theory of stellar structure, the thermal behavior of a spherical cloud of gas, isothermal gas sphere, theory of thermionic currents, pattern formation, population evolution [2, 3, 6,16,17] and have attracted much attention in recent years.
