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 ¹⁶O ions incident on a polyethylene target. These relativistic hypernuclei were studied with large gap spark chambers that were electronically triggered by the low momentum K⁺ meson produced in association. Analysis of 22 events yields a mean lifetime τ(¹⁶Z_Λ)=(0.86_-0.26+0.33)×10^-10 sec.NUCLEAR REACTIONS Hypernuclei (¹⁶O,¹⁶N_Λ or ¹⁶O_Λ) K⁺, $E=2.1$ GeV/nucleon, polyethylene target, σₜ roughly measured; mean lifetime of mass 16 hypernuclei measured.
