نویسنده
چکیده
The S0-pairing gap in semi-infinite nuclear matter is evaluated microscopically using the effective pairing interaction recently found explicitly in the coordinate representation starting from the separable form of the Paris NN -potential. Instead of direct iterative solution of the gap equation, a new method proposed by V. A. Khodel, V. V. Khodel and J. W. Clark was used which simplifies the procedure significantly. The gap ∆ obtained in our calculations exhibits a strong variation in the surface region with a pronounced maximum near the surface.

In this work we calculate the 1 S 0 gap energies of Λ hyperons in neutron star matter. The calculation is based on a solution of the BCS gap equation for an effective G-matrix parameterization of the Λ−Λ interaction with a nuclear matter background, presented recently by Lanskoy and Yamamoto. We find that a gap energy of a few tenths of MeV is expected for Λ Fermi momenta up to about 1.3 fm −1....

The breathing-mode giant monopole resonance is studied within the framework of the rel-ativistic mean-field (RMF) theory. Using a broad range of parameter sets, a systematic analysis of constrained incompressibility and excitation energy of isoscalar monopole states in finite nuclei is performed. A comparison is made with the incompressibility derived from the semi-infinite nuclear matter and w...

The fundamental structure of the full set of solutions of the BCS P2 pairing problem in neutron matter is established. The relations between different spin-angle components in these solutions are shown to be practically independent of density, temperature, and the specific form of the pairing interaction. The spectrum of pairing energies is found to be highly degenerate. Typeset using REVTEX

We study fragmentation of small atomistic clusters via molecular dynamics. We calculate the time scales related to fragment formation and emission. We also show that some degree of thermalization is achieved during the expansion process, which allows the determination of a local temperature. In this way we can calculate the break-up temperature as a function of excita-tion energy, i.e. the frag...
