Proton-proton and proton-deuteron elastic scattering has been measured for incident laboratory energy from 50 to 400 GeV; minimum |*| values were, for p-p, 0.0005 (GeV/ c) 2 , and for p-d, 0.0008 (GeV/c) 2 . From the differential cross sections we have determined the ratios of the real to imaginary parts of the forward scattering amplitude, ppp and p pd , for p-p and p-d scattering. Using a Glauber approach and a sum-of-exponentials form factor we obtain p pn for p-n scattering.Dubna,

The first hypernuclei production experiment using a beam of heavy ions from the Lawrence Berkeley Laboratory Bevatron is described. Mass 16 hypernuclei were produced by 2.1 GeV/ nucleon 0 ions incident on a polyethylene target. These relativistic hypernuclei were studied with large gap spark chambers that were electronically triggered by the low momenturn K' meson produced in association. Analysis of 22 events yields a mean lifetime 7( +) = (0. 86+0'&3&) x 10 sec.NUCLEAR REACTIONS Hypernuclei ( 0, NA or OA) E+, E =2.1 GeV/nucleon, polyethylene target, 0'~roughly measured; mean lifetime of mass 16 hypernuclei measured.
