摘要：
It is shown that in a light-cone representation of nucleons soft-pion theorems which are violated in instant-form quark models can be recovered with suitable choices of parameters of the model. Instantaneous terms must be included for the soft-pion limit. The proton form factors are fit up to q2=3 (GeV/c)2 in this model. © 1990 The American Physical Society.
