The 
spin-observables presented in this section were extracted
from the quasifree scattering data taken during experiments E385 and E387.
The quasifree region was split into 10 MeV bins which seemed to provide
reasonable statistics to extract the observables while still providing a
good picture of the energy dependence. The results from the data taken
with the normally polarized 
beam, which includes
, 
, and P (induced polarization), are listed on
tables 
and for 
and
, respectively.

These results are shown in graphical format in figure compared to
results from recent Faddeev type calculations [Wit96] of the deuterium
observables. The analyzing power and
induced polarization seem to be in reasonable agreement. Both show
rather small magnitudes. However, in 
there is significant
disagreement between the 
data and both the Faddeev calculations
and the 
data.

excitation spectra are shown at the top. The dashed line show the results
of Faddeev calculations of the spin-observables for the deuterium
reaction. The vertical dotted line indicate the energy loss for free np
scattering.
The results for the sideways and longitudinal incident beams for the
reaction are compiled in tables
and , respectively. Similarly, the
spin-observables from the

longitudinally polarized beams, respectively.

The results from the sideways and longitudinal data are also shown in
figures and , respectively. Generally, it seems that
the Faddeev calculations predict the 
results fairly well for
all the in-plane spin observables with possible exception of
. The 
and 
results also seem to
follow the same trends.

The 
results have been presented for completeness but it is
unclear if any conclusions regarding quasifree scattering can be drawn
from them. The range of energy
loss over which data was gathered, as shown at the top of figure
for example, spans a momentum transfer of 
fm
to
fm
. In this range quasifree scattering is just
beginning
to turn on. That is, the momentum transferred to the stationary nucleon in
the nucleus is barely sufficient for knock-out, which defines quasifree
scattering. Also, in this region of momentum transfer measured at
the pion effects are going to be very small.
From figure one can see that the expected longitudinal
contribution from the pion is around zero. This supported by the fact that
the longitudinal spin observable 
is essentially zero in figure
. To look for a change in nuclear response functions due to an
enhanced pion field it is reasonable to look other momentum transfers where
the pion residual interaction in non-zero.
It is worth mentioning at this point that data were taken at 
primarily because 
was considered to be a possibly interesting
angle. That meant that the INPOL detector had to gather 
data
while the KSU detector gathered data at 
.
