摘　　要：The effect of short-range and tensor correlations on nuclear symmetry energy is investigated by using realistic nuclear momentum distribution n(k).For finite nuclei,the n(k)is discussed in detail within an analytical model that allows inclusion of both short-range and tensor correlation effects in a physically very transparent way.The equation of state of symmetric nuclear matter is calculated by using realistic n(k)parameterization.The tensor-force induced short-range correlations are shown to have a significant impact on the behavior of symmetry energy.
