Abstract
It is shown that relativistic effects, considered in the framework of a relativistic quark model constructed in infinite momentum frame, improve the argument between theory and experiment for delta->Ngamma transition. They enlarge the magnitudes of the amplitudes AP(1/2) and AP(3/2) and suppress with increasing Q2 the magnetic form factor of delta->Ngamma transition in comparison with proton magnetic form factor. The additional inclusion of not large QCD-inspired mixings of multiplet (56',0+) into the N and the delta improves further the agreement with experiment for this form factor and permits to describe its Q2-dependence at Q2 Ngamma transition are obtained. It is predicted that the electric form factor is positive at Q2</
