Two controversial states considered to have a large alpha cluster strength, the 0+ state at 8.54 MeV and the 1 state at 11.7 MeV of Ti44, were examined in the (6Li,d) reaction at E(6Li)=50 MeV. The 11.7-MeV state was scarcely observed, if at all, for θlab=5–35°, and the angular distribution for the 8.54-MeV state was unlike that of an L=0 transition. These results indicate that both states are unsuitable candidates for the lowest states of the parity doublet band of Ti44 in the alpha cluster model.
