In the cohisionahy induced dissociation of the photoexcited B 'II, state of Li,, is found that the 2 ' Psn which has Li(2 \*P)+Li(2 \*S) as products, it fine-structure state is PrcferentiaIIy produced. The 2 \*Psfl and 2 2P1/2 atomic Li state production was measured by observing the fluorescence pro
