Clusters and Shell-Structure in Light Nuclei
Thomas Neff, Hans Feldmeier and Robert Roth Gesellschaft für Schwerionenforschung mbH, Planckstraße 1, 64291 Darmstadt, Germany †Institut für Kernphysik, TU Darmstadt, Schlossgartenstraße 9, 64289 Darmstadt, Germany Abstract. Light nuclei in the p-shell are studied in the Fermionic Molecular Dynamics model. No a priori assumptions are made with respect to cluster structure or single-particle en...
متن کاملPseudospin, supersymmetry and the shell structure of atomic nuclei
The evolution of single-particle energies with varying isospin asymmetry in the shell model is an important issue when predicting changes in the shell structure for exotic nuclei. In many cases pseudospin partner levels, that are almost degenerate in energy for stable nuclei, are relevant in extracting the size of the shell gaps. A breaking of the pseudospin symmetry can affect the size of thes...
متن کاملShape and shell-structure of nuclei towards neutron drip line
In nuclei along the β stability line the nucleons are bound at least by 7–10MeV, and the magic numbers in those nuclei are well known as N (or Z) = 8, 20, 28, 50, 82, and 126. In contrast, in nuclei away from the β stability line the presence of nucleons with binding energy much smaller than 8MeV leads to a unique shell-structure. Consequently, magic numbers may be changed and the nuclei, which...
متن کاملParticle-vibration coupling and shell structure of exotic nuclei
We discuss the effects of particle-vibration coupling on the shell structure of nuclei near the neutron drip line by choosing, as examples, 10Be and 24O cores. In particular, we calculate the energy shifts of single-particle neutron states induced by the interaction with collective modes. In the case of the 10Be core, the coupling to 2+ states is responsible, within our model, of narrowing the ...
متن کاملthe underlying structure of language proficiency and the proficiency level
هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
