The measurement of nuclear Generalized Parton Distributions (GPDs)represents a valuable tool to understand the structure of bound nucleons and the phenomenology of hard scattering off nuclei. By using...
Quadrupole Moments of Collective Structures at Ultrahigh Spin in $^{157}$Er and $^{158}$Er: A Challenge for Understanding Triaxiality in Nuclei
Quadrupole Moments Collective Structures Ultrahigh Spin $^{157}$Er and $^{158}$Er Challenge Understanding Triaxiality Nuclei

2011/1/4
The merits of searching for \eta -mesic nuclei by use of the (\pi, N) reaction at J-PARC is discussed, by comparison with an old experiment with the same reaction at BNL in 1980's. The importance of a...

2011/1/4
Photoproduction of \eta mesons off light nuclei (d, 3He, 7Li) has been measured at the tagged photon beam of the Mainz MAMI accelerator with the combined Crystal Ball/TAPS detection system. Special at...
Localization in light nuclei
Localization light nuclei

2011/1/6
We investigate the presence of spatial localization in nuclei using a method that maps the nucleon same-spin pair probability and is based on the density-matrix. The method is used to study spatial lo...

Two nucleon correlations Three- and four-body systems Nuclear spectral function
font style='font-size:12px;'>
2011/1/6
Recent BNL and Jlab data provided new evidence on two nucleon corre-lations (2NC) in nuclei. The data confirm the validity of the convolution model, de-scribing the spectral function (SF) of a correla...

2011/1/6
The properties of the low-lying 2+ states in the even-even nuclei around 132Sn are studied within the quasiparticle random phase approximation. Start-ing from a Skyrme interaction in the particle-hole...
