要旨:
The determination of nucleus-nucleus potentials is important not only to
describe the properties of the colliding system, but also to extract
nuclear-structure information and for modelling nuclear reactions for
astrophysics. We present the first determination of double-folding potentials
based on chiral effective field theory at leading, next-to-leading, and
next-to-next-to-leading order. To this end, we construct new soft local chiral
effective field theory interactions. We benchmark this approach in the
16O-16O system, and present results for cross sections computed for
elastic scattering up to 700 MeV in energy, as well as for the astrophysical
$S$-factor of the fusion reaction.
