Interpretation of Recurring Minima in Elastic Scattering at Large Momentum Transfers

Maxima and minima recently reported in forward elastic scattering at moderately high energy and large momentum transfer are correlated with exceptional points $\alpha =0, -1, -2, \cdots$ on the $P^{\prime }$ and $\omega$ Regge trajectories. An Ansatz for the Regge residue functions is given that reproduces the qualitative features of the new data. This interpretation leads to further predictions that can be experimentally checked.
