Abstract

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 E_α = 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).
