The NΔγ Form Factors — •C. Arias Tobeña, S. Deister, J.A. Eden, and M.F. Gari — Ruhr Universität Bochum, Universitätstrass. 150, D-44780-Bochum
We extend [1] our [2-4] relativistic, non-perturbative and self-consistent calculations for the NNπ, NNρ, NNω and NNє form factors. As no free parameters enter the calculations, the tensor couplings κNNρ and κNNω are now explicity determined.
We further develop this relativistic and non-perturbative work by presenting
calculations for the NΔγ, NΔπ and NΔρ transition form factors.
We compare our results with experiment over a wide range of momentum transfers and discuss
the importance of the findings in relation to the e.m. form factors of the neutron.
