Decay of hypernuclei

We present a nonrelativistic transition potential for the weak strangeness- changing reaction Lambda N --> NN. The potential is based on a one meson ex change model (OME), where, in addition to the long-ranged pion, the exchang e of the pseudoscalar K, eta, as well as the vector rho,omega, K* mesons is considered. Results obtained for different hypernuclear decay observables are compared to the available experimental data.
