Abstract
We identify the source of a discrepancy between and found by Isgur and Llewellyn Smith. We find that the discrepancy disappears when virtual pair production for longitudinal-momentum transfers is included. Our result rectifies the discussion by Isgur and Llewellyn Smith of soft nonperturbative effects at presently available values of .
