The priorities for future hypernuclear research call for high
resolution spectroscopy and coincidence experiments. The
neutral meson spectrometer (NMS) could form the backbone
of high precision 
hypernuclear studies
via the 
reaction and 
weak decays.
The energy resolution of less than 1 MeV for this device would
enable significant advances in determining the structure of 
hypernuclei. Note that a whole new class of 
hypernuclei will be accessible via this reaction which converts
a proton into a 
.
Hypernuclei afford a unique environment
for the study of this four fermion weak interaction, which is the
analog of the parity-violating 
weak process
(
). There has been progress in the measurement of weak
decay lifetimes and branching ratios at the AGS. Precise measurements
of the ratios of neutron to proton stimulated emission in non-mesonic
decays are very important and would impact strongly on the
validity of the 
rule, observed to hold in many
other weak decay processes.
A crucial measurement for analysis of
the s-shell hypernuclei is to measure the weak decays of 
H,
which can be achieved with the NMS via the 
H
reaction. The NMS can also be used to measure
the 
from the weak-decay of light s- and p-shell hypernuclei
following production in the 
reaction.
The free space 
decay is strongly suppressed in hypernuclei
(except the lightest ones) due to Pauli blocking, and the non-mesonic
process 
dominates. For S=-2, additional modes like
become accessible.
