Abstract. Low-energy dipole excitations have been investigated theoretically in N=50 Sr and Zr, several N=82 isotones and the Z = 50 Sn isotopes. For this purpose a method incorporating both HFB and multi-phonon QPM theory is applied. A concentration of one-phonon dipole strength located below the neutron emission threshold has been calculated in these nuclei. The analysis of the corresponding ...

متن کاملLow-Energy Magnetic Dipole Radiation in Open-Shell Nuclei.
Low-energy M1 strength functions of ^{60,64,68}Fe are determined on the basis of large-scale shell-model calculations with the goal to study their development from the bottom to the middle of the neutron shell. We find that the zero-energy spike, which characterizes nuclei near closed shells, develops toward the middle of the shell into a bimodal structure composed of a weaker zero-energy spike...
متن کاملN = 82 shell quenching below 13250 Sn 50
The influence of nuclar structure on the r-process nucleosynthesis can best be studied within the ”waiting-point” concept [1]. Within this framework, the successful reproduction of the global isotopic abundances (Nr, ) as well as remaining deficiencies have been interpreted by our group as signatures of nuclear structure near the neutron dripline [1]. Pronounced abundance troughs prior to the N...
متن کاملShell Closures in Exotic Nuclei
Inspired by the recent experiments [1]-[3] indicating unusual doubly magic nucleus O which lies just at the neutron drip-line and encouraged by the success of our relativistic mean-field (RMF) plus state dependent BCS approach for the description of the ground state properties of the drip-line nuclei [23]-[27], we have further employed this approach, across the entire periodic table, to explore...
