$^6$He-triton cluster states in $^9$Li
  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 $K^\pi=1/2^-$ band and their neutron configuration is similar to that of the $K^\pi=0^+_2$ band in $^{10}$Be.
