Title: Experimental examination of the lowest alpha cluster states in sup 44 Ti

Abstract

Two controversial states considered to have a large alpha cluster strength, the 0{sup +} state at 8.54 MeV and the 1{sup {minus}} state at 11.7 MeV of {sup 44}Ti, were examined in the ({sup 6}Li,{ital d}) reaction at {ital E}({sup 6}Li)=50 MeV. The 11.7-MeV state was scarcely observed, if at all, for {theta}{sub lab}=5--35{degree}, and the angular distribution for the 8.54-MeV state was unlike that of an {ital L}=0 transition. These results indicate that both states are unsuitable candidates for the lowest states of the parity doublet band of {sup 44}Ti in the alpha cluster model.
