Abstract
A nuclear resonance fluorescence experiment with one of the newly developed highly efficient EUROBALL cluster detectors has been performed on the $\ensuremath{\gamma}$-soft nucleus ${}^{196}\mathrm{Pt}$. Magnetic dipole excitations were observed between 2 and 3.5 MeV excitation energy. They are interpreted as the main fragments of the scissors mode based on the measured excitation strengths and branching ratios. A strong $\ensuremath{\gamma}$ decay, which we believe to be an $E2$ decay of the scissors mode to the ${2}_{1}^{+}$ state, is observed. It allows an extraction of the effective boson quadrupole charges in the interacting boson model.
