【 摘 要 】

Isospin, density and electromagnetic waves in asymmetric nuclear matter with the addition of electrons (ANM) are studied. The use of a semi classical relativistic approach based on the Wigner function and its Vlasov like equation to study ANM allowed to obtain the dispersion relations for small amplitude oscillations. The small longitudinal wave case results were equivalent with a previous work that used a somewhat different formalism called generating function. The small transverse wave results, that cannot be obtained directly using the generating function formalism, were also obtained.
