A reported splitting of the lowest T = 2 strength in /sup 44/Ti has been confirmed by examining resonances in the /sup 40/Ca(..cap alpha.., ..gamma..) /sup 44/Ti reaction at excitation energies in the region of 9.28--9.36 MeV. A level at 9298 +- 2 keV in /sup 44/Ti is found to have ..gamma..-decays to the 1/sup +/, T = 1 level at 7216 keV and to a T = 0 level at 3756 keV. The former transition is attributed to a T = 2 component in the 9298 keV level, with, however, the main T = 2 strength remaining in the level at 9338 +- 2 keV, as reported previously. Evidence is presented for a weak (9338 ..-->.. 3756), ..delta..T = 2 transition in addition to the dominant (9338 ..-->.. 7216), ..delta..T = 1 ..gamma..-decay branch. The two levels at 9298 and 9338 keV are interpreted as an isospin-mixed doublet. The perturbing matrix element is estimated to be 16 +- 3 keV, and the unperturbed T = 2 state to lie at 9330 +- 4 keV.
