Linearly Rising Regge Trajectories and the Isovector Form FactorF1V(t)

A simple ansatz for the isovector Dirac form factor is examined. A fit to an approximate dipole form is achieved, and deviations from this form are also accounted for. A ${\rho }^{\prime }$ is no longer necessary; the next vector meson used in the saturation has a mass of approximately 1.7 GeV. The fit also gives a $\rho \mathrm{NN}$ coupling constant which has the right value, as well as providing a good value for the necleon charge radius.
