Exchange terms in the two--nucleon induced non--mesonic weak decay of $\Lambda$--hypernuclei

E. Bauer, G. Garbarino

The contribution of Pauli exchange terms to the two--nucleon induced non--mesonic weak decay of ${}_{\Lambda }^{12}$C hypernuclei, $\Lambda NN\to nNN$ ($N=n$ or $p$), is studied within a nuclear mat…
