Abstract:

For the determination of the

~{144}Sm-\alpha

optical potential we measured the angular distribution of

~{144}Sm(\alpha,\alpha)~{144}Sm

scattering at the energy

E_{lab} = 20 MeV

with high accuracy. Using the known systematics of

\alpha

-nucleus optical potentials we are able to derive the

~{144}Sm-\alpha

optical potential at the astrophysically relevant energy

E_{c.m.} = 9.5 MeV

with very limited uncertainties.
