Abstract

Cross sections for the ⁴⁴Ti(α, p)⁴⁷V reaction which significantly affects the yield of ⁴⁴Ti in supernovae were measured in the energy range 5.7MeV ≤ E_c.m. ≤ 9 MeV, using a beam of radioactive ⁴⁴Ti. The cross sections and the deduced astrophysical reaction rates are larger than the results from theoretical calculations by about a factor of 2. The implications of this increase in the reaction rate for the search of supernovae using space-based gamma detectors are discussed.
