Effects of deformation in the three-body structure of 11Li

Abstract

11Li is studied within a three-body model 9Li+n+n where the core is allowed to be deformed and/or excite. In particular, we include reorientation couplings and couplings between the two bound states of 9Li. Contrary to the other examples studied within this model, we find that core excitation does not affect the structure of 11Li significantly. Reorientation couplings of the deformed 9Li can change the ground state of 11Li from a predominantly two neutron s1/2^2 configuration into a p1/2^2. In addition, we see no evidence for the existence of significant d-wave strength in its ground state, as opposed to the prediction by shell model. A comparison with shell model is presented.
