Abstract:
The subject of this thesis is the investigation the magnetic dipole transition for J = 2-3
in titaniumlike Rhenium in the 3d4 ground term at the Heidelberg EBIT. Different theoretical approaches are taken into account since it is the first time one has resolved the
Hyperfinesplitting as well as the Zeeman–effect at the HD–EBIT. Moreover there was
no case found in literature in which the Hyperfinesplitting of this transition was resolved
for any titaniumlike element. The results are given by two independent, theoretical
models to E1 = 3; 433666(23) eV and E2 = 3; 433676(19) eV. The value obtained in
this work, combined with the values found in literature for other elements, is used to
create an interpolation of this isoelectronic sequence for the unmeasured elements from
Z = 47 - 83.
