Existing data sets for these reactions are sparse and inconsistent, despite their importance for testing exact calculations of the A=3 system. This work presents final results from the first simultaneous measurement of the absolute 90 deg. cross sections for the two-body photodisintegration of 3H and 3He at using tagged photons with energies Eg = 18-50 MeV, and comparison with theoretical predictions based on charge-symmetric models.
