Abstract

The reaction 3He(γ, π+)3H is studied in the impulse approximation using realistic wave functions for photon energies up to 5 MeV above threshold. The calculation is performed with Blomqvist-Laget amplitudes and Fermi motion is taken into account. At threshold we obtain the reduced cross section a(3He) = 120 μb, which is in good agreement with the recent experiment of Argan et al.
