Three-triton states in {sup 9}Li

We investigate whether three-triton states appear or not in excited states of {sup 9}Li. We also search for a signature of the gaslike three-triton state, which is partly an analogy to the the case of the three-{alpha} state in {sup 12}C (Hoyle state). For this purpose, we use both three-triton and {alpha}+t+n+n wave functions to describe the low-lying states of {sup 9}Li and take into account the coupling effect between them. We show that the states in which the three-triton components dominate indeed appear below the three-triton threshold energy, although the root-mean-square radii of those states are not so much expanded in comparison with the gaslike state of three {alpha}'s.
