Response function beyond mean field of neutron - rich nuclei
The damping of single-particle and collective motion in exotic isotopes is a new topic and its study may shed light on basic problems of nuclear dynamics. For instance, it is known that nuclear structure calculations are not able, as a rule, to account completely for the empirical single-particle damping. In this contribution, we present calculations of the single-particle self-energy in the ca...
متن کاملShape evolution and Gamow-Teller β-decay of neutron-rich A∼100 nuclei within beyond-mean-field approach
Our recent investigations represent an attempt to the self-consistent description of exotic phenomena in neutron–rich A∼100 nuclei [1, 2] within the complex Excited Vampir variational model with symmetry projection before variation using a realistic effective interaction in a large model space. The triple shape coexistence and the shape evolution in the N=58 Sr and Zr isotopes, the shape evolut...
متن کاملProton-rich Nuclei at and beyond the Proton Drip Line in the Relativistic Mean Field Theory
Ground state properties of proton-rich odd-Z nuclei in the region 55 ≤ Z ≤ 73 are studied in the relativistic mean field (RMF) theory. The RMF equations are solved by using the expansion method in the Harmonic-Oscillator basis. In the particle-particle channel, we use the state-dependent BCS method with a zero-range δ-force, which has been proved to be effective even for neutron-rich nuclei. Al...
متن کاملNeutron Halos in Heavy Nuclei Relativistic Mean Field Approach
Assuming a simple spherical relativistic mean eld model of the nucleus, we estimate the width of the antiproton{neutron annihilation ( n) and the width of antiproton{proton ( p) annihilation, in an antiprotonic atom system. This allows us to determine the halo factor f , which is then discussed in the context of experimental data obtained in measurements recently done on LEAR utility at CERN. A...
متن کاملContinuum QRPA response for deformed neutron-rich nuclei
We discuss properties of the quadrupole collective excitation of the deformed neutronrich nucleus Mg within the framework of quasi-particle random phase approximation (QRPA). We first solve the coupled-channels equations to obtain the single-particle levels, and construct the ground state by treating the pairing correlations in the BCS approximation. We then solve the QRPA equation using the re...
