Electromagnetic N->Delta transition and neutron form factors
arXiv:hep-ph/0412421 · doi:10.1103/PhysRevLett.93.212301
Abstract
The C2/M1 ratio of the electromagnetic N->Delta(1232) transition, which is important for determining the geometric shape of the nucleon, is shown to be related to the neutron elastic form factor ratio G_C^n/G_M^n. The proposed relation holds with good accuracy for the entire range of momentum transfers where data are available.
