Abstract
Tests of unitary symmetry in nuclei by coherent reactions leading to hypernuclei are examined. Starting from the two-particle amplitudes for elastic and strangeness-changing meson-baryon reactions, a pseudo-potential is derived which couples the nucleus and hypernucleus channels. Using experimental cross sections, numerical estimates for various processes are made in order to appraise the feasibility of experiments, and it is found that experimental tests are possible with present techniques.
