Query: The $l$ dependence of the helion optical model potential and the
  undularity of the $l$-independent equivalent   The relationship between $l$-dependence and undularity of the optical model
potential (OMP) is studied for the case of the elastic scattering of 33 MeV
\nuc{3}{He} on $^{58}$Ni. The relationship that emerges follows the general
features of the same relationship found for the proton OMP presented in
arXiv:1705.07003. The general background is also presented in that reference.
