AbstractThe helicity amplitude A(1/2)(P) for the electromagnetic transition gamma*N --> N*(1535) is investigated. It is found that, a new mechanism gamma* --> q (q) over bar plays an important role in order to improve the description of this transition. On one hand, the A(1/2)(P) is decreased to fall in the data range at the photon point Q(2) = 0, while on the other hand, the new mechanism makes the function A(1/2)(P)(Q(2)) to decrease more slowly vs increasing Q(2), as required by the data.
