| Abstract |
The equation for thermionic emission has been derived from Eyring`s absolute reaction rate theory, which can be used to evaluate the reflection coefficient. The reflection coefficient γ was found to be γ=0.273×10^(-5)◎ where, M is the atomic weight of the metal, ρ the density of the metal, n the number of free electrons assigned to an atom, and T the absolute temperature of the metal. The values of the relflection coefficient for pure metals at various temperatures were computed and found to be very small. |
