We calculate the total cross section for the reaction /sup 12/C(..gamma..,..pi../sup -/)/sup 12/N/sub g.s./ and study its energy dependence in the threshold region. Contrary to previous theoretical analyses, we find agreement between theory and experiment using a sigma x epsilon interaction. Our results depend strongly on the inclusion of all pion partial waves and a correct treatment of the isospin dependent terms in the pion-nucleus optical potential.
