摘要：

A method is proposed to extend the hard scattering picture of Brodsky and Lepage to transitions between hadrons with orbital angular momentum l = 0 and l = 1. The use of convariant spin wave functions turns out to be very helpful in formulating that method. As a first application we construct a light-cone wave function of the nucleon resonance N* (1535) in the quark-diquark picture. Using this wave function and the extended hard scattering picture, the N - N* transition form factors are calculated at large momentum transfer and the results compared to experimental data. As a further application of our method we briefly discuss the pi - a1 form factors in an appendix.
