Abstract
The collective excitation spectra of the rho meson triplet in neutron matter is studied, with particular emphasis on the breaking of the dis crete p <----> n symmetry leading to a mass splitting among the charge states (rho(+/-),rho(0)) and modification of the form of the polariza tion tenser. The effect of the tensor interaction in the rho nucleon v ertex on the dispersion characteristics is studied.
