  Because of Pauli suppression effects the $N\pi$ decay of the free $\Lambda$
is not of importance in hypernuclei with $A\geq 10$. Rather the decay of such
hypernuclei proceeds via the nucleon-stimulated mode $\Lambda N\rightarrow NN$,
analysis of which presents a considerable theoretical challenge and about which
there exists only a limited amount of experimental information. Herein we
confront existing data wih various theoretical analyses which have been
developed.
