  The production of neutron rich $\Lambda$-hypernuclei via the
($K^-_stop$,$\pi^+$) reaction has been studied using data collected with the
FINUDA spectrometer at the DA$\Phi$NE $\phi$-factory (LNF). The analysis of the
inclusive $\pi^+$ momentum spectra is presented and an upper limit for the
production of $^6_\Lambda$H and $^7_\Lambda$H from $^6$Li and $^7$Li, is
assessed for the first time.
