We investigated theoretically the geminate electron--ion recombination in the limit of large electron mean free path by using the concept of diffusion in energy space. The energy diffusion equation is derived and the energy diffusion coefficient is evaluated. An analytical expression for the escape probability of the electron--ion pair is derived. It reproduces the numerical results very well which were obtained previously by using a Monte Carlo method. Experimental implications of the present theoretical findings are discussed.
