Continuum effects in nuclear structure and reactions

Structural properties of exotic nuclei close to the drip lines are
influenced by the continuum. For medium-mass to heavy nuclei, the
nuclear Energy Density Functional (EDF) is an efficient method to
describe structural properties and to account for the particle continuum.
In the light of recent problems encountered when extending
the EDF theory to account for nuclear symmetries, I will present an
analysis of the restoration of the particle number invariance in the
EDF framework and an application of the symmetry-conserved EDF
to finite nuclei.

For light nuclei, a fundamental description of structural and re-
action properties starting from two- and three-nucleon forces is
desirable and requires to properly treat the continuum. The ab
initio no-core shell model when combined with the resonating-group
method (NCSM/RGM) is capable of describing simultaneously
both bound and scattering states of light nuclei.
Using similarity-renormalization-group evolved chiral interactions, I will present
applications to light-nuclei binary scattering processes when accounting
for the chiral three-nucleon interaction.
