Abstract
Using the Argonne V18 interaction, renormalized with the Lee-Suzuki method, we study nuclei around the N = 20 island of inversion. We include 5 major oscillator shells, in a no-core approach, using the hybrid multi-determinant method reaching up to few hundreds Slater determinants. Although qualitatively in agreement with the experimental levels, the calculated BE2 do not show the same amount of collectivity seen experimentally.
