Nuclear recoil /sup 18/F reactions in CH/sub 3/CHF/sub 2/ have been investigated throughout the effective pressure range 0.3--190 atm. The principal reaction channel is F-to-HF abstraction for which the combined yield from quasithermal and energetic processes in the presence of 5 mole% H/sub 2/S additive is 83.4% +- 0.2%. A reaction mechanism is proposed that involves the organic product forming channels F-for-F, F-for-..cap alpha..H, F-for-..beta..H, F-for-CH/sub 3/ and F-for-CHF/sub 2/. The results are compared with those reported for the /sup 18/F+CH/sub 3/CF/sub 3/ system.
