Linear responses to solenoidal and to potential electric fields are ca
lculated using equations for quasiclassical Green's functions. Damping
of THz plasma oscillation is determined by dielectric relaxation and
is small. Relaxation of branch imbalance due to elastic scattering mak
es the Carlson-Goldman mode damped. (C) 1997 Elsevier Science B.V.
