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