Several variants of sources for nuclear polarized negative ion production have been proposed and tested. The simple adaptation of a high intensity polarized proton source for nuclear polarized H[sup [minus]] production has been examined. A pulsed current of H[sup [minus]] up to 0.15 mA has been obtained. For the examination of H[sup [minus]] production in the collision of H atoms with exited alkali atoms, the conversion of a low energy atomic beam from an RF dissociator into negative ion flow by using cesium vapor target with discharge has been tested. The formation of H[sup [minus]] ions by simultaneous operation of the RF dissociator and a discharge in the cesium target has been observed. Finally, the polarization of nuclei in molecules by collisions with electron polarized (optically pumped) alkali atoms, nuclear polarization in molecules, induced by chemical reaction in cyclic molecules, and the possibility of using this for ion sources are discussed.
