Résumé |
One of the recently developed approaches capable of describing both bound and scattering
states in light nuclei simultaneously is the No-Core Shell Model with Continuum
(NCSMC) [1,2]. I will present latest NCSMC calculations of weakly bound states and
resonances of exotic halo nuclei such as $^6$He and $^{11}$Be and discuss strong E1 transitions and
photo-dissociation of $^{11}$Be. I will also present our results for unbound nuclei such as $^7$He,
$^9$He and $^{11}$N and highlight the role of chiral NN and 3N interactions. Finally, I will review
our recent results for $A{=}12$ nuclei with $^{12}$N calculated including its $^{11}$C+p breakup channel
and discuss the role of E1 excitations in $^{12}$C in experimental determination of its $2^+$
quadrupole moment.
