Abstract

For the determination of the ¹⁴⁴Sm-\ensuremathα optical potential we measured the angular distribution of ¹⁴⁴Sm(\ensuremathα,\ensuremathα)¹⁴⁴Sm scattering at the energy E_lab=20 MeV with high accuracy. Using the known systematics of \ensuremathα-nucleus optical potentials we are able to derive the ¹⁴⁴Sm-\ensuremathα optical potential at the astrophysically relevant energy E_c.m.=9.5 MeV with very limited uncertainties.
