Angular correlations of the /sup 6,7/Li(..pi../sup +- /,pn) cross sections were measured in a wide angular range at T/sub ..pi../ = 70 MeV. The components of the two-nucleon absorption processes were extracted, and the angular distributions of the cross sections were obtained. Strong asymmetries about 90/sup 0/ were observed for the reactions /sup 6,7/Li(..pi../sup +- /,pn), and the cross sections were much larger than that of /sup 3/He. These results show the importance of the sigma/sub 11/ component in pion absorption on T = 1 nucleon pairs for p-shell nuclei.
