The Mg24(He3,t)24Al reaction was studied at E(3He)=420 MeV. An energy resolution of 35 keV was achieved. Gamow-Teller strengths to discrete levels in Al24 were extracted by using a recently developed empirical relationship for the proportionality between Gamow-Teller strengths and differential cross sections at zero momentum transfer. Except for small discrepancies for a few weak excitations, good agreement with previous Mg24(p,n) data and nuclear-structure calculations using the USDA/B interactions in the sd shell-model space was found. The excitation energy of several levels in Al24 of significance for determination of the Mg23(p,γ)24Al thermonuclear reaction rate were measured. Results are consistent with two of the three previous (He3,t) measurements, performed at much lower beam energies. However, a new state at Ex(24Al)=2.605(10) MeV was found and is the third state above the proton separation energy.
