Expectations from nuclear structure models
are tested
by data from high resolution transfer reactions
performed at the Munich Q3D spectrograph.
The concept of supersymmetry
relates in an algebraic way parts of the low lying
spectra of nuclei such as
194Pt, 195Au, 195Pt, and 196Au.
These even-even, even-odd,
odd-even and odd-odd nuclei
are related by interchange of bosonic and fermionic
degrees of freedom.
To support a systematic understanding
our present studies aim to provide best spectroscopic information
on the odd-odd nucleus 196Au
and on neighbouring nuclei as the neutron rich isotopes
up to 202Au.
Excellent spectra with high counting statistics
have been obtained
with a new focal plane detector and with polarized beam currents
of up to 2 µA on the target.
We discuss the determination of excitation energies, spin, parity
and spectroscopic factors from
angular distributions
of (d→,t), (d→,4He),
(3He,d) and (4He,d).
Further activities at our facility as studies of
octupole multi-phonon excitations
in 228Th, 230Th and 232U
and of superdeformation in 14C and 236U
will be summarized.
The work was supported by the DFG (C4-Gr894/2-3 and Jo 391/2-1),
DGI (BFM2002-03315) and MLL.
