Gamow-Teller transitions from {sup 24}Mg to {sup 24}Na were studied via the (t,{sup 3}He) reaction at 115A MeV using a secondary triton beam produced via fast fragmentation of 150A MeV {sup 16}O ions. Compared to previous (t,{sup 3}He) experiments at this energy that employed a primary {alpha} beam, the secondary beam intensity is improved by about a factor of five. Despite the large emittance of the secondary beam, an excitation-energy resolution of {approx}200 keV is achieved. A good correspondence is found between the extracted Gamow-Teller strength distribution and those available from other charge-exchange probes. Theoretical calculations using the newly developed USDA and USDB sd-shell model interactions reproduce the data well.
