Spin distribution measurements provide a unique tool for investigating the angular momentum (ℓ) dependence of fusion hindrance in heavy ion-induced reactions. We report evaporation residue-gated spin distributions for the *1*9F+*1*9*7Au system at beam energies in the range of 86 –112 MeV using the gas-filled recoil separator HYRA coupled with a 4π spin spectrometer. Comparison with statistical model calculations reveals strong attenuation of the fusion probability at higher partial waves, while at lower ℓ values the fusion probability is less affected. The derived average fusion probability, (P&sub(fus)) = 0.61, is in agreement with previous reports. The analysis confirms that quasifission occurs predominantly at higher angular momenta, coinciding with the region where fission dominates. This demonstrates that spin distribution measurements at sufficiently high excitation energies can reveal the details of the ℓ-dependence of fusion suppression mechanisms, information that is not available from average fusion probabilities derived from cross section analysis. – (EPJ Web of Conferences ; Vol. 378) .
