摘要：

He-3(gamma, ppi+/-) reactions are simultaneously measured for tagged photon energies of 380 less-than-or-equal-to E(gamma) less-than-or-equal-to 700 MeV. The yield ratio for the two channels, under the same kinematical and dynamical conditions, is found to be 0.90+/-0.07. Implications of this ratio in terms of the delta component in the ground state of He-3 are examined. An alternate interpretation of this ratio as due to an admixture of isospin T = 1/2 and 3/2 transition amplitudes in a pure isovector interaction is also presented.
