Whence the odd-even staggering in nuclear binding?
W. A. Friedman, G. F. Bertsch
We explore the systematics of odd-even mass staggering with a view to identifying the physical mechanisms responsible. The BCS pairing and mean field contributions have A- and numb…
Odd-even mass differences from self-consistent mean-field theory
G. F. Bertsch, C. A. Bertulani, W. Nazarewicz +2
We survey odd-even nuclear binding energy staggering using density functional theory with several treatments of the pairing interaction including the BCS, Hartree-Fock-Bogoliubov,…
Collectivity-induced quenching of signatures for shell closures
M. Bender, G. F. Bertsch, P. -H. Heenen
Mass differences are an often used as signature and measure for shell closure. Using the angular-momentum projected Generator Coordinate Method and the Skyrme interaction SLy4, we…
Accuracy of BCS-based approximations for pairing in small Fermi systems
N. Sandulescu, G. F. Bertsch
We analyze the accuracy of BCS-based approximations for calculating correlation energies and odd-even energy differences in 2-component fermionic systems with a small number of pai…
Many-Body Approximations in the sd-Shell Sandbox
R. A. Sen'kov, G. F. Bertsch, B. A. Brown +2
A new theoretical approach is presented that combines the Hartree-Fock variational scheme with the exact solution of the pairing problem in the finite orbital space. Using this for…
Systematics of the first 2+ excitation in spherical nuclei with Skryme-QRPA
J. Terasaki, J. Engel, G. F. Bertsch
We use the Quasiparticle Random Phase Approximation (QRPA) and the Skyrme interactions SLy4 and SkM* to systematically calculate energies and transition strengths for the lowest 2+…
