We report on the current status of our experiment employing a hybrid atom-ion trap for investigating the interaction between OH* anions and rubidium atoms. The experimental setup consists of an octupole rf ion trap with thin wires providing sufficient optical access to combine the ion trap with a dark-spontaneous-force optical trap for the atoms. The motional and internal temperature of the anions will be probed by photodetachment spectroscopy.
