A new measurement of the circular polarization P/sub ..gamma../ of the 1081-keV ..gamma.. line in /sup 18/F has been performed. The result is P/sub ..gamma../(1081 keV) = (2.7 +- 5.7) x 10/sup -4/. This result, when averaged with those of recent measurements in /sup 18/F, sets an upper constraint for the absolute value of the coupling constant f/sub ..pi../ of the weak ..pi..NN interaction of Vertical Barf/sub ..pi../Vertical Bar< or =1.5 x 10/sup -7/. .AE
