The gamma ray tracking array GRETINA started operation at MSU in spring 2012. It was installed at the target position of the S800 spectrometer at NSCL. Currently it has 7 modules each with four 36-fold segmented Ge detector, covering 1-p solid angle in the angular range of 60 to 90 degrees. The tracking detectors have the unique ability of resolving the energy and position of the individual...

The interest for the investigation of medium mass nuclei near the drip lines goes beyond the frontier of nuclear structure and dynamics. Detailed knowledge of the properties and decay rates of nuclei near the drip lines are required by the simulation of many astrophysical objects. The structure and dynamics of proton-rich A~70 nuclei and neutron-rich A~100 nuclei are influenced by shape...

Nature's heaviest naturally occurring odd-odd isotopes, 176Lu and 180Ta have a pair of high and low-K levels at low energies formed by parallel or anti-parallel coupling of the unpaired proton and neutron to give a total projection, K = | Omega p ± Omega n |. One consequence of this is the formation of a long-lived 9- state in 180Ta, the only naturally occurring nuclear isomer, with a...

A systematic experimental programme has been started to derive the evolution of quadrupole collectivity near the heaviest stable doubly-magic nucleus Pb-208. Here, B(E2;0+ -> 2+)-values are being measured via relativistic Coulomb excitation. Despite the fact that the energy, E(2+), and strengths, B(E2;0+ -> 2+), of the first 2+ state in even-even nuclei is one of the key quantities in nuclear...

Giant Resonances are collective modes of excitation of atomic nuclei, providing useful information on nuclear structure and on the effective nucleon-nucleon interaction. It is possible to excite such resonances with different probes as for example: photons, charged particles or heavy ions, followed by subsequent decays by emission of particles and γ’s. Below particle threshold, a large...

Neutron-rich isotopes represent a steady source of new information on the behavior of the nucleus. Sometimes, unexpected phenomena occur such as halo-nuclei or the disappearance of the well-established magic numbers. Spin-isospin parts in the nucleon-nucleon interaction, e.g., the proton-neutron tensor force (in particular, the strongly attractive monopole parts) are expected to modify shell...
