Abstract
The suppressed ratio of () to () pion absorption cross sections on has an important contribution from NN′ intermediate states, where N′ denotes a interaction. The order-of-magnitude energy variation of this ratio, from stopped pions to pions above the (3,3) resonance, is reproduced in calculations using a unitary isobar model. We predict a strong asymmetry in the angular distribution of the ratio of higher pion energies.
