N2 - A number of 6- and 5- states in 26Al were studied in the region of excitation energy 5-15 MeV with the 24Mg(α, d)26Al reaction at Eα = 63.7 MeV. The data were analyzed within the framework of zero-range DWBA theory for a macroscopic deuteron-cluster transfer as well as for a microscopic two-nucleon transfer, and compared with our previous results on the 25Mg(3He, d)26Al reaction. Several 6- and 5- states are newly proposed. Five 6- states previously assigned as T = 1 were weakly observed in the present (α, d) reaction, which should excite only T = 0 states. The isospin breaking (α, d) transition to the 6-1, T = 1 state was found to be an order of magnitude larger than a second-order exact-finite-range DWBA calculation for the successive transfer processes of (α-3He-d) and (α-t-d).
