Erratum: isospin dependence of pion absorption on nucleon pairs
Journal Article
·
· Phys. Rev. C; (United States)
The relative sign between the NN' and N..delta.. intermediate states was incorrect in the computer code that produced the predictions in this paper. Correcting this error makes negligible changes in the predictions of sigma/sub 1/, the cross section for absorption by T = 0 NN pairs. The angle-averaged ratio R (Fig. 3) is also negligibly affected by this correction. The major effect of this sign error is to reverse the asymmetry of the T = 1 cross section sigma/sub 3/(theta) about theta = ..pi../2. An example of this is shown for T/sub ..pi.., lab/=255 MeV. Note that the authors prediction in the paper of a prominent backward peaking in R (theta) at this energy now becomes, as corrected, a prediction for strong forward peaking. At T/sub ..pi..,lab/=65 MeV the asymmetry is now in agreement with the observed backward-peaked cross section, but the predicted angular distribution is still flatter than the data.
