Neutron-proton mass difference in finite nuclei and the Nolen-Schiffer anomaly
Ulf-G. Meißner, A. M. Rakhimov, A. Wirzba +1
The neutron-proton mass difference in finite nuclei is studied in the framework of a medium-modified Skyrme model. The possible interplay between the effective nucleon mass in fini…
Remarks on N N -> N N pi beyond leading order
C. Hanhart, A. Wirzba
In recent years a two-scale expansion was established to study reactions of the type N N -> N N pi within chiral perturbation theory. Then the diagrams of some subclasses that are…
Nucleon-nucleon potential in finite nuclei
U. T. Yakhshiev, Ulf-G. Meißner, A. Wirzba +2
We consider the spin-isospin-independent central part of the residual nucleon-nucleon potential in finite spherical nuclei taking into account the deformation effects of the nucleo…
Electromagnetic form factors of bound nucleons revisited
Ulughbek T. Yakhshiev, Ulf-G. Meißner, Andreas Wirzba
We investigate the possible modifications of the nucleons' electromagnetic form factors in the framework of a modified Skyrme model allowing for nucleon deformation and using reali…
Casimir Interaction among Objects Immersed in a Fermionic Environment
Aurel Bulgac, Andreas Wirzba
Using ensembles of two, three and four spheres immersed in a fermionic background we evaluate the (integrated) density of states and the Casimir energy. We thus infer that for suff…
