N2 - We calculate the relative absorption ratio of a pion by T = 0 and T = 1 nucleon pairs in the He isotopes measured recently by Ashery et al. Standard theory based on Δ-isobar intermediate excitations agrees with the experimental observation that for energies around the resonance, pion absorption by a T = 1 nucleon pair is strongly suppressed.
