Pairing and shell gaps in nuclei
نویسنده
چکیده
The pairing contribution to the odd-even oscillations in the nuclear binding energies is considered in the framework on the nuclear shell model. Schematic and realistic Hamiltonians are used to understand the trends related to pairing and shell gaps. Detailed results are shown and discussed for the calcium isotopes. Results are also shown for carbon, oxygen and neon as well as the overall trends for all nuclei.

ov 2 00 8 Shell gaps and pn pairing interaction in N = Z nuclei
We analyze the observed shell gaps in N = Z nuclei determined from the binding energy differences. It is found that the shell gaps can be described by the combined contributions from the single-particle level spacing, the like-nucleon pairing, and the proton-neutron pairing interaction. This conclusion is consistent with that of Chasman in Phys. Rev. Lett. 99 (2007) 082501. For the double-close...
متن کاملNuclear pairing gap: how low can it go?
The pairing gap for 53Ca obtained from new experimental data on the masses of (52-54)Ca has the smallest value yet observed. This is explained in the framework of the nuclear shell model with schematic and realistic Hamiltonians as being due to shell gaps around the low-j orbital 1p(1/2). Minima in the pairing gaps for all nuclei are shown and discussed.
متن کاملShell-model Calculations with a Skyrme-type Effective Interaction
Shell-model calculations for the s-d shell nuclei and Sn isotopes are performed using Hartree-Fock wave functions and two-body matrix elements based upon the SGII Skyrme-type density-dependent interaction. We reproduce the spectra of several nuclei from the beginning to the end of the s-d shell. The experimental pairing gaps for the Sn isotopes are also obtained from calculations in the general...
متن کاملSuperheavy nuclei in relativistic effective Lagrangian model
Isotopic and isotonic chains of superheavy nuclei are analyzed to search for spherical double shell closures beyond Z = 82 and N = 126 within the new effective field theory model of Furnstahl, Serot, and Tang for the relativistic nuclear many-body problem. We take into account several indicators to identify the occurrence of possible shell closures, such as two-nucleon separation energies, two-...
