I^+ states of ^<26>Mg through the (α, ^3He) reaction at 81MeV

The ^Mg (α, ^3He) ^Mg reaction leading to seven 1^+ states, proposed previously by proton scattering at 201 MeV and by the (α, ^3He) reaction at 50MeV, was measured at E_α=80.9MeV. The cross sections obtained were analyzed within the framework of the exact-finite-range distorted wave Born approximation. The spectroscopic factors for a d_ transfer to 1^+ states were compared with those predicted by sd shell model calculations. Two of the 1^+ states were found to have a simple (d_d_) structure consistent with the shell model picture. Others with too large d_ transfer strength were ascribed owing to a mixture of other nearby states with J^π values other than 1^+ in referring to a recent compilation
