Abstract

The phenomenon of s-wave intruder orbits is examined for the Be12 and Be14 isotopes. Although Be11 has an s-wave ground state, a three-body model of two neutrons + Be10 can only reproduce the properties of Be12 if the valence neutrons occupy mainly the (p1/2)2 configuration with about 25% admixture of (sd)2 configurations. For Be14, the possibility of low-lying s-wave states in Be13 means that a wide range of models are compatible with the existing radius and momentum measurements, though some s admixture is necessary for binding. We show which kinds of momentum and Coulomb breakup measurements will be necessary to elucidate the structure of the Be14 halo. © 1996 The American Physical Society.
