Response Function of Asymmetric Nuclear Matter
The charge longitudinal response function is examined in the framework of the random-phase approximation in an isospin-asymmetric nuclear matter where proton and neutron densities are di erent. This asymmetry changes the response through both the particle-hole interaction and the free particle-hole polarization propagator. We discuss these two e ects on the response function on the basis of our...
متن کاملVariational Calculations of Asymmetric Nuclear Matter
We report on variational calculations of the energy E(p, ß) of asymmetric nuclear matter having p = p +pp = 0.05 to 0 .35 fm-~, and ß = (P -p~)lp = 0 to l . The nuclear hamiltonian used in this work consists of a realistic two-nucleon interaction, called °i<, that fits the available nucleon-nucleon scattering data up to 425 MeV, and a phenomenological three nucleon interaction adjusted to repro...
متن کاملSpatially inhomogeneous phase of asymmetric nuclear matter
We study the isospin singlet pairing in asymmetric nuclear matter with nonzero total momentum of the condensate Cooper pairs. The corresponding BCS equations are derived and solved within the finite temperature retarded realtime Green’s functions formalism. The quasiparticle excitation spectrum is four-fold split compared to the usual BCS spectrum of the symmetric, homogeneous matter. A two-fol...
متن کاملIsovector response function of hot nuclear matter with Skyrme interactions.
We investigate the role of the effective nucleon-nucleon interaction in the description of giant dipole resonances in hot nuclei. For this purpose we calculate the response function of hot nuclear matter to a small isovector external perturbation using various effective Skyrme interactions. We find that for Skyrme forces with an effective mass close to unity an undamped zero sound mode occurs a...
متن کاملIsovector Collective Response Function of Nuclear Matter at Finite Temperature
We study isovector collective excitations in nuclear matter by employing the linearized Landau-Vlasov equation with and without a non-Markovian binary collision term at finite temperature. We calculate the giant dipole resonance (GDR) strength function for finite nuclei using Steinwedel-Jensen model and also by Thomas-Fermi approximation, and we compare them for 120Sn and 208Pb with experimenta...
