Home | Publication List | Members ABOUT OUR RESEARCH GROUP
The proton-neutron degree of freedom of atomic nuclei and its impact on nuclear structure phenomena at low angular momentum represent a broad field of modern many-body quantum physics and the major topics of this research group. Relevant information is obtained by our group mainly in nuclear experiments using high-resolution gamma-ray spectroscopy and a variety of state-of-the-art techniques.
PROTON-NEUTRON MIXED-SYMMETRY STATES
The recent discovery of proton-neutron asymmetric multi-phonon states
of nuclei in the mass region around A=100 at low excitation energies
represents a step forward in modern nuclear structure physics. The
group is currently working at the NSL at SUNY at Stony
Brook on the extension of the data base for these new low-energy
proton-neutron asymmetric, collective nuclear structures.
FURTHER INFORMATION
QUASI-DEUTERON CONFIGURATIONS
Low-spin states with different proton-neutron structure (different isospin quantum number) are furthermore investigated in heavy nuclei at the N=Z line in the chart of nuclides. The so-far most extensive quasideuteron structure in a heavy N=Z nucleus was observed in gamma-ray spectroscopy experiments on the nucleus 50Mn performed by the group at the Wright Nuclear Structure Laboratory at Yale University in New Haven, Connecticut, U.S.A.
NUCLEAR PHYSICS WITH A FREE-ELECTRON-LASER
A new method of experimental nuclear physics using a high-quality
gamma-ray beam produced by Compton-backscattering of a
Free-Electron-Laser (FEL) photon beam has recently been pioneered by
our group in collaboration with scientists from Israel, Russia, and the
U.S. These experiments were performed at the Duke Free Electron Laser Laboratory
at Duke University
in Durham, North Carolina, U.S.A.
This new technique opens up an unprecedented level of accuracy and
sensitivity in various aspects of nuclear gamma-ray scattering
experiments and will enable us to gain deeper insight into the dipole
response of nuclei at the particle emission threshold.
FURTHER INFORMATION
INTERNATIONAL COLLABORATION
Extensive collaborations with experimental and theory groups in Germany, Europe, Japan, and the U.S.A. completes the exciting research work of the group. (publication list)
JOBS AND CONTACT
Senior researchers, Ph.D. students (Doktoranden), graduate students
(Diplomanden oder vergleichbar Abschluss-orientiert) and even younger
enthusiastic students are welcome for collaboration and for deepening
their skills in modern nuclear structure experiments, nuclear theory,
information technology (IT), and digital communication.
We frequently offer open positions and support for stipends and
fellowships for interested persons from the Universität zu Köln, from
Germany or from abroad.
The collaborations might involve trips to nuclear structure experiments
at other research facilities in Europe (e.g., Rex-Isolde at CERN) or in the U.S.
(e.g., Wright
Nuclear Structure Laboratory at Yale University or the Duke Free Electron
Laser Laboratory at Duke
University).
Please contact or anyone else of our team for information on joining the research group or on participating in selected work.
FUNDING
This group is funded by National Science Foundation.
