6He-triton cluster states in9Li

Cluster states in ${}^{9}$Li are investigated with calculations of a ${}^{6}$He-$t$ cluster model. Results suggest ${}^{6}$He-$t$ cluster states near the ${}^{6}$He-$t$ threshold energy. These states construct a ${K}^{\ensuremath{\pi}}=1/{2}^{\ensuremath{-}}$ band and their neutron configuration is similar to that of the ${K}^{\ensuremath{\pi}}={0}_{2}^{+}$ band in ${}^{10}$Be.
