We discussed the stability against disturbances of liquid lithium flows for the target and coolant of BNCT (Boron 4eutron Capture Therapy) using accelerators, which makes cancers and tumors curable with cell-level selections. The )bject of our research is the thin and high-speed plane sheet jet / film flow (on a guide plate) of liquid lithium in a sighvacuum because of the ambience using accelerators, and it serves both as a target of accelerators and as a coolant or the target itself. In this paper, we made the linear stability analysis suitable to the physical features of thin plane ,heet jets of liquid lithium in a high-vacuum. As the results, we proved that the anti-symmetric sinusoidal wave has no lispersion and the symmetric dilatational wave has a strong dispersion in which the very slow phase velocity is )roportional to the wave number, when the thickness of a plane sheet jet of liquid lithium is sufficiently thinner than the vave length.
