Abstract

Recently, the energy spectrum of 10Li was measured upto 4.6 MeV, via one-neutron transfer reaction d(9Li, p)10Li. Considering the ambiguities on the 10Li continuum spectrum with reference to new data, we report the con guration mixing in the ground state of the two-neutron halo nucleus 11Li for two different choices of the 9Li+n potential. For the present study, we employ a three-body (core+n+n) structure model developed for describing the two-neutron halo system by explicit coupling of unbound continuum states of the subsystem (core+n), and discuss the two-neutron correlations in the ground state of 11Li.

Author comments upon resubmission

Dear Editors,
Following Referee remarks the suggested minor corrections has been
implemented in this version of manuscript.
Best Regards,
Jagjit

List of changes

Considering the Referee remarks following changes has been made:
1. In sec. 3 we have added "with standard choice of spin-orbit interaction" just before equation 5.
2. In summary we have added
"However our results show different configuration mixing for two different choices of core+n potential. In order to conclude which configuration is likely in the ground state of 11Li, we need further investigations of the reaction observables that are sensitive to partial wave content of the ground state."
3. Minor typo in abstract and third paragraph of intro
d(9Li,p)11Li --> d(9Li,p)10Li
