Abstract

The short-lived radionuclide ⁴⁴Ti, which has been observed in space by γ -ray astronomy, is believed to be produced in supernovae during the alpha;-rich freeze-out by α capture on ⁴⁰Ca. This reaction has been studied in inverse kinematics using the recoil mass spectrometer DRAGON at the ISAC facility at TRIUMF in Vancouver, Canada. A large energy range was covered corresponding to the temperature range of T9 ∼1- 2. 8 for freeze-out conditions. A preliminary analysis shows additional contribution to the total ⁴⁴Ti yield between the resonances measured by prompt γ -ray studies.
