Abstract

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