Sup 10–11]Li and [sup 13–14]Be Studied by Projectile Fragmentation and pp-RPA

Abstract

The level ordering in the unbound nuclei 10Li and 13Be is established on firm basis using a time dependent projectile fragmentation model, comparing to experimental data and using structure inputs obtained from a semi‐phenomenological core‐vibration coupling model of two‐neutron halo nuclei. As a consistency test we show that the energy spectra of some Beryllium isotopes obtained by using pp‐RPA predict the same shell ordering as extracted from the reaction model vs. data analysis and that the well known structure of 11Li is reproduced.
