BS>The experimental plan is described including a diagram of the apparaths. The measurement of C /sub nn/ was made in runs of 64 and 74 hours duration using a beam of about 1.4 x 10/sup 9/ protons sec/sup -1/ intercepting the target. The most important contribution was from p-p scattering events causing the operation of three counters which were set up on one side and only the first of three counters set up on the other side, with the assymetry in such measurements defined by the formula e=RR +LL--LR-RL/RR +LL +LR+RL;for a scattering angle of 90 deg in the center of mass it should be found that RR = LL and LR = RL. The value of ssymmetry was e = +0.192 plus or minus 0.035. (J.R.D.)
