Dubach, J

The ..lambda..N ..-->.. NN non-mesonic decay mode of hypernuclei is examined in a model that employs a weak, strangeness-changing meson exchange potential in a Fermi gas model of the hypernucleus. Results are in good agreement with recent experiments for A = 11 and A = 12 hypernuclei. The calculations suggest that the ratio of proton-stimulated to neutron-stimulated decays and the ratio of parity-violating to parity-conserving decays are particularly sensitive to the details of the model. Finally, preliminary results using a more sophisticated shell model of the hypernucleus are discussed. 13 refs., 2 tabs.
