A high resolution inelastic proton scattering experiment on 58Ni at extreme forward angles, was performed at RCNP. This method has been proven to be an excellent tool to study the dipole response of nuclei. Measurements performed at afew hundred MeV incident energy and at 0 are particulary suited for the excitation of the isovector spin-flip M1 (IVSM1) resonance. The properties of the IVSM1 are e. g. used in the description of neutral-current neutrino interactions in supernovae. Another interesting phenomena is the so called quenching, which describes a systematically overestimation of the experimentally obtained magnetic dipole strength by microscopic model predictions. In this work first result towards an extraction of the magnetic dipole strength with a multipole decomposition analysis will be shown.
