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.
