Nucleon Polarisabilities from Compton Scattering on the Deuteron
Harald W. Griesshammer, Gautam Rupak
An analytic calculation of the differential cross section for elastic Compton scattering on the deuteron at photon energies ωin the range of 25-50 MeV is presented to next-to-next-…
Photoproduction of quasi-bound omega mesons in nuclei
E. Marco, W. Weise
We propose the (gamma,p) reaction as a means of producing possible quasi-bound states of omega mesons in nuclei. We use an effective Lagrangian, based on chiral SU(3) symmetry and…

Chaos and isospin symmetry breaking in rotational nuclei
J. A. Sheikh, A. T. Kruppa, N. Rowley
For nuclei with N = Z, the isospin degree of freedom is important and, for deformed systems, rotational bands of different isospin may be expected at low excitation energies. We ha…
Nuclear Shadowing and the Optics of Hadronic Fluctuations
