3. 24Na is produced through the reaction 26Mg(d,a)4Na. A 0.2 mm thick magnesium foil is irradiated for 1 h by a current of 130 mA of 22 MeV D* ions in a cyclotron. The foil has a much larger area than the cross-section of the beam. What is the specific activity of 24Na if the magnesium foil (3 cm?) contains 0.003% Na and the cross-section for the reaction is assumed to be 25 mb? (3 points)
