Relaxation of excited electrons in an electron gas: A mean-field approach with charge and spin polarizations

The relaxation rate of excited electrons in a paramagnetic electron gas is calculated. The theory is based on the charge and spin response functions and the local-field methodology of generalized mean-field descriptions. A link between this treatment and the kinetic treatment for the relaxation phen...
