We report on the current status of our experiment, which combines an 8-pole radio-frequency trap for OH- anions and a dark-spontaneous-force optical trap for rubidium atoms. The laser-cooled atoms serve as an ultracold buffer gas for the trapped anions. The anions final internal state is probed by means of electron photodetachment spectroscopy (PDS). We further discuss how PDS can be used for determining the final translational temperature of the anions.
