The differential scattering cross section ( sigma ) for the elastic scattering of 18.7 Mev alpha particles from C/sup 12/ is measured from 165 to 179 deg (c.m.). A rapid rise is observed in sigma in this angular range. It is found that sigma does not pass through a peak near 180 deg , but rises steadily to a value of 1.2 plus or minus 0.1 barn/sterad at 180 deg . (T.F.H.)
