Dynamics and thermodynamics in spinor quantum gases
H. Schmaljohann, M. Erhard, J. Kronjäger +2
We discuss magnetism in spinor quantum gases theoretically and experimentally with emphasis on temporal dynamics of the spinor order parameter in the presence of an external magnet…
Gamma-induced background in the KATRIN main spectrometer
K. Altenmüller, M. Arenz, W. -J. Baek +123
The KATRIN experiment aims to measure the effective electron antineutrino mass with a sensitivity of 0.2 eV/c using a gaseous tritium source combined with t…
Solving the stellar 62Ni problem with AMS
I. Dillmann, T. Faestermann, G. Korschinek +11
An accurate knowledge of the neutron capture cross sections of 62,63Ni is crucial since both isotopes take key positions which affect the whole reaction flow in the weak s process…
Experimental study of the electric dipole strength in the even Mo nuclei and its deformation dependence
M. Erhard, A. R. Junghans, C. Nair +6
Two methods based on bremsstrahlung were applied to the stable even Mo isotopes for the experimental determination of the photon strength function covering the high excitation ener…
Bose-Einstein condensation at constant temperature
M. Erhard, H. Schmaljohann, J. Kronjäger +2
We present a novel experimental approach to Bose-Einstein condensation by increasing the particle number of the system at almost constant temperature. In particular the emergence o…
Photodisintegration studies on p-nuclei: The case of Mo and Sm isotopes
C. Nair, A. R. Junghans, M. Erhard +10
In explosive stellar environments like supernovae, the temperatures are high enough for the production of heavy neutron-deficient nuclei, the socalled p-nuclei. Up to now, the know…
