Further Studies on D.C. Noise in Plasma Due to Electron-Ion Collisions

D.C. noise in the plasma is generated due to the charge-oscillations set in the colliding ions by the electrons of the electron-ion pairs in equilibrium with the ambient temperature of the plasma. These electron-ion pairs are formed on otherwise free space. This d.c. noise radiation is a coupled one having a maximum value of the frequency denoted by a cut-off frequency which is determined by the density of ions in the plasma. The d.c. noise radiation temperature for this coupled noise is 851 K at ambient temperature of 273 K for singly charged particles of ionized hydrogen type gas molecules with low charge-carrier average density of electrons or ions i.e
in a typical star dust of interstellar space(s) in the galaxy/galaxies with a characteristic temperature of 1021 K having a cut off frequency of 21.29 x 1012 Hz where it is assumed that there exit a randomly oriented average d.c. electric field of 10 V/m due to accumulation of charge-carriers of oppositely charged particles in some distant places in the galaxy/galaxies.
